Science Diet Reviews

The humane society has recommended this food. Haven't had any problems thus far. Just started the adult indoor from the kitten version. Will get back to my reviews whether good or bad.

All these complaints for Blue Buffalo, Hill's and Nutro sound the same. Same illnesses, same symptoms! Something fishy going on. We as humans die of certain diseases, and we don't blame the burger we ate or the food. Cats and dogs can get illnesses over time. It's not the food… it’s YOU! Fake reviews indeed. BTW my cats thrive on Big Macs! PS: My cats don't eat Big Macs. But they thrive on it. Do you believe me?

After reading all the negative reviews on this site, I just wanted to express how happy I have been with Science Diet for over two decades. My current three dogs did just fine when the formula changed, and I have had no problems with their health their entire lives.

I used Science Diet dry dog food since 2009 when I got my first Toy Fox Terrier starting with the canned and then dry puppy food and moved up to the next age for dogs after age 1. I also used it for the next 2 dogs I got, a Toy Fox Terrier and a Yorkie. They all did great on it. Due to a chronic illness I suffer from, I had to find very special new homes for my two Terriers but kept my Yorkie. Sometime around the end of 2013, I noticed she became very lethargic, would not eat or drink much and started having accidents and she was housebroken. She had another accident and I noticed it had blood in it.

I am so upset with what seems to me to be a money maker for your company and the vets.. Dog food that I can only buy through prescription... Come on... it only makes cents for you and the vets.. This is just crazy... Lost another customer.... Please explain this action if you can... Like I said I think it only makes cents and not sense...

I am going to make my story to the point as much as I can. 3yr old lab eating SD Lite perfectly healthy..... THEN THIS: Starts showing signs of bloat, vomits, agitated, gacking, drooling, licking, stomach extending. Dog is having normal bowel movements. Was at night many hours after his dinner. Sickness lasting several or more hours. He did not throw up after eating which is deceiving. 2 emergency vet visits. First one they operated due to gas and unidentified objects. (My dog licks and eats things to make himself throw up.) They gave him meds and changed him to SD gastro food. Second visit... extreme gas. Many tests and 3,000 dollars later, they didn't find anything wrong. Vet said some form of Pica (which I knew was not). Told to keep diary and on 24 hr watch.

I just bought a bag of Science Diet and my older dog got sick yesterday. I thought it was something she ate. My other older dog got sick the next day, diarrhea, vomiting. Neither one will touch the food now. They will both consume other food. For some reason, I still have the bag..2043- pb305310...L133 51090 2x4 bopp hs. I will discontinue use immediately.

My Springer Spaniel a very active dog has ate Science Diet last two years and not had a problem. I bought a new bag approx March 13, 2014. I noticed the dog food had a strong almost like vitamin supplement smell. Just not sure but did not think much of it. However, dog has been vomiting and lethargic. At first, I thought dog ate something outside but after she started drinking a lot more water than normal, vomiting, and becoming lethargic I thought I should check online for any recalls or other pet owners with problems. Looks like there is a problem. Something is just not right and wish I had went with my gut when I first thought the food smelled unusual.

I believe that the bag of Science Diet dog food I bought beginning of March was contaminated and made my dogs very ill. They both had the same symptoms of lethargy, diarrhea, vomiting, fevers and they would not touch their food. They are both labs and LOVE to eat so this was very unusual. I did not suspect the food at first, but my lab Leo kept pushing his bowl toward us when we tried to feed them. We would literally hand feed it to them and make them eat, not realizing we were making it worse. They would smell it and walk away.

In the last 18 days I have purchased 36 cans of SD WD for my diabetic dogs, the recipe for the food must have changed between each 12 cans I purchased. One set was EXTREMELY wet and mushy, the next was thicker but didn't seem to have all the regular ingredients. I just opened the 2nd of the last 12 cans and they have both been so dry that I had to throw them out, they are not expired so I can only assume that quality control is non-existent at Hills. I'm currently lobbying my vet for new prescriptions for a different diabetic food. It would be easier to just buy more SD food but I'm not willing to risk my dogs' health for my convenience. Anyone else having these issues?

I have called in to report the problem my dog and cat are having because it’s identical and they are both on Hill's Science Prescription Diet foods. I hope others are doing the same. It is important to do more than discuss it here. People need to report the problem to Hills Science so they can address it asap. Also report it to the store and to your vet so they are aware of it.

I picked up a new bag of SciDiet Light on Friday 2/28/14 from Petco. Tonight I opened the bag and noticed a weird clear plastic-looking substance in the bag. I thought it was probably part of the bag that had fallen inside during packaging, and although alarmed, grabbed a paper towel and reached inside to remove the 'plastic'. UGH. It turned out to be a slimy, sticky substance that I removed and dropped in the sink. I went back to the bag to see if anything else was in there and was horrified to see more of the slimy crud as well as three large winged insects climbing up from the bottom of the bag!!! I closed it immediately to keep the bugs from escaping then put the slimy crud back into the bag (and was thrilled to see even more bugs crawling around in the bag....) zipped the top, rolled the top down and securely taped it shut. I plan to return it to the store tomorrow!!!

My dog has ate SD for years. I just bought a new bag a couple weeks ago and after reading all the posts I am now positive that the bag I bought is bad. He never misses a meal and from the time I opened the bag he wanted nothing to do with it. He ate it and got really sick. After a couple of weeks I bought a different food and he seems to be doing much better.

I purchased a bag of the dry and 4 cans of the wet S/D food this week. The vet told me to absolutely keep this AWAY from my other healthy cat. That alone made me weary to feed it. My cat has bladder stones caused by Natural Balance LID, which recently moved to the diamond factories, surprise surprise, and was prescribed this food as a last resort to surgery. She would NOT eat the wet food. She tried to cover it, and would not even eat her favorite food on the same plate three inches away. Worst, when she ate less than a tablespoon of the dry food, even mixed with her normal food, she vomited. And I don't mean just a little. She threw up seven times in less than a few minutes and to the point that she was vomiting white foam.

Back in November 2013, I tried SD I/D for my GSD because the vet wanted him on it because of diarrhea. He was in good health at the age of 13 1/2, but after eating SD I/D he started coughing. I knew this was not normal. He started laying around and he was not that type of dog even at his age... This happened suddenly after eating this CRAP!!! He started hanging his head low and could not walk at all. His body temp. dropped low and the vet came over and said he has severe bloat and I didn't know. I wish I knew the symptoms so I could of got to the vet sooner. With bloat they could die very fast.

My four dogs have been eating Science Diet Advanced Fitness Original Formula for the past year or so and have been fine. After purchasing a new bag tonight however, they are vomiting. I am very concerned. The timing and correlation seems so clear that I wanted to research if anyone else was having this problem - if there was a recall or known poisoning of the food or anything, and found this site. I'm going to switch to another brand of food to see if it alleviates the problem. They better investigate what's going on. I will be extremely upset if there are any longer term or more serious effects.

We have fed our schnauzer Hills Science Sensitive Skin for about 2 years without any noticeable problems until I read these posts. He did have blood on his stools sometimes, now that I think back about it. But since he wasn't really suffering in any other way we thought it was nothing to be alarmed about (and, it's also worth mentioning that he did have diarrhea and vomiting off and on but we never associated it with the food. Our thinking was that just because the brand was recommended by his former vet).

I first noticed my cat asking for his daily night time wet cat food sooner than usual. Then I noticed he was trying to eat people food. I could not understand what was going on. I usually have the kids feed our cat, but today I fed him and noticed he has not been eating his Science Diet cat food (The new formula). I called the place I bought it from complaining that I got a bad bag of food. Then I did some research and found this site. Thank you to everyone who posted. I will be taking my cat to the vet tomorrow to make sure no damage has occurred because I fed him this food.

Used Science Diet Adult Formula for a year & a half with not too many problems for my beloved 13 year old Maine Coon Leo. Just bought a bag of the "new & improved" formula. 2 weeks ago he began violently vomiting alternately, clear & foamy white, also uncountable trips to the box, disgusting diarrhea, sometimes mixed with what appeared to be blood! Thinking it was a tainted canned food treat, I stupidly continued feeding him this, and the conditioned worsened. He got a completely disturbing look to his face, eyes and walk, weird crying, etc. Found him in a corner of the basement hiding as a dying animal will sometimes do.

Started a new bag in mid-January, "New and Improved" Formulation, which we had been using for years (well, not the New and Improved). The 3 cats walked away from it. While having one cat walk away is not that uncommon (cats... they are so picky sometimes), 3 is unusual. Came back from work, food had been eaten. Shortly thereafter, Ziggy, the smallest cat (he is a very lean guy) was salivating seriously, chest was soaked, he was listless, was trying to drink unsuccessfully. He threw up water.

I have been feeding my boxer Science Diet all of her life - almost 6 years now. On January 5th, I purchased a new bag of food and within days my dog started to having what I now believe to be adverse reaction to the new bag of food. She began having diarrhea. She is a chow hound and nothing keeps her from finishing a meal, but she began not eating at all. Initially she would take boiled chicken and rice, but eventually turned her nose up to that. I took her to the vet, who sensed she had some abdominal discomfort, but wanted to take a conservative route with antibiotics and a continued bland diet. We went home and began the course of antibiotics; however, she still wouldn't eat, only consuming pieces of chicken I fed her by hand.

I have had my 13 year old border collie "Benn" on Hill's KD for about three years ago for elevated kidney readings one time around age 9.5 yrs. Once on the KD Benn's kidney readings returned to normal. All was well until we opened a recent bag of food on Saturday, February 8th, 2014. Benn had three meals out of the bag and became very ill. This dog has never missed a meal in his life. He LIVES TO EAT! But there is something wrong with this bag of food. He would not eat it this morning and was almost non-responsive, panting, and I suspect in pain. We went to the vet immediately... CBC, Blood Chem, x-rays all have revealed nothing except a little gas in his stomach. He was running a temp of 104.5, he is extremely lethargic to non-responsive, heart rate up, labored panting type breathing & standing with his head in the corner of the room. He would not drink, would not be affectionate like he normally is and WOULD NOT EAT.

I can only state factually that this dog food is making all 4 of my dogs vomit since I bought the latest bag on 1/17/2014 - but based on other reviews below, I suspect it is producing life-threatening damage internally (see other reviews below which proceed from sickness to death). Within 2 weeks of starting a new bag of Hill's Science Diet for Sensitive Stomach, all 4 of my medium-to-large dogs are gagging and vomiting. The only dog that is fine is the Chihuahua who eats a different brand of dog food that's appropriate to his size and age. My dogs have no variables in their diet, and twice daily each gets 1 cup of dog food, which is 80% another brand, and 20% Hill's Science Diet for Sensitive Stomach (the Hills has always been good, for years, for keeping them regular).

RE: NEW FORMULA... Read between the lines, people: MY FAVORITE QUOTE FROM THEIR OWN BAG: "High quality ingredients make litter box cleanup easy!" (Yeah... Translation #1: When your cat(s) are dead, you can throw the whole litter box thing away. Translation #2: Their food is designed for your convenience - tiny little turds for you to clean up; BUT, it's NOT designed for your cat's health or convenience.)

When we adopted our little 4.5 kg 4 year old Schipperke 3 weeks ago, we were told that Hills Science Diet Small Bites was what he had been fed so we bought a bag and at $35 for a 4 kg bag it is expensive. We got him home & he wouldn't touch it, so we just left it & he did eat some when he got really hungry then he vomited it all up. We put it down to excitement at his new home but decided to feed him other food.

My 4 year old rescue dog, Pretzel, has done fairly well on Science Diet Sensitive Stomach. There have been times when his stool was just right and others when it was very soft & runny, and he has always had very stinky gas. Starting in early January 2014 he started having bad diarrhea, scratching constantly and loosing hair. He has also been very angry and quick to react with other dogs which is the polar opposite of his true personality. After going to the vet, he was put on a steroid & probiotics. The steroids made him drink water like crazy! Which made him pee all the time, sadly in the house as well as outside. The probiotics that were supposed to harden his stool were not working at all which is highly unusual.

I have fed my cat this for several years. He has always had stomach issues, loose stool and occasional vomiting. Very thin. Even with this food. I bought and opened a new bag on Jan. 18th. Everyday he would eat and immediately throw up. Finally I thought there has to be something wrong with this food. I started researching other foods to see what I could find that would be comparable. I was looking and comparing ingredients. Imagine my surprise when I looked at the one I had been feeding thinking I was helping my poor cat, to discover the main ingredient was Brewers Rice and no meat at all. It does list Liver Flavoring however.

I am having the same Science Diet issues as many others. Both my cats had eaten the hairball light formula for years and loved it. Recently noticed them acting funny, crying, vomiting, and then finally refusing to eat. I switched the food out with a can we had and they gobbled it up! Upon investigation, discovered ALL of these same cases, some leading to death. I have emailed Science Diet and warned my family & friends. Just unbelievable. There can be this many of the same stories. Hoping there is no serious damage, and will be switching brands immediately.

Every can of hill's KD dog food there is some missing, today I opened a can and about 1/3 of the can had AIR in it, I have called hills and was told it was their processing, Sorry I don't buy air for well over $1.00 a can..I also buy Pedigree for my other dogs and guess what no air. Is this another scam like breyers Ice cream going from 1/2 gal to 1.5 qts. and raise the price, well if hill's does not correct this problem with their dog food, I will find another food for my dog.

Tried SD ideal gluten free and it caused vigorous vomiting within 15 minutes of only having 1 tablespoon. Was downright scary... She threw up multiple times but then seemed ok after that. Will be watching her closely next several hours and NOT be feeding her SD. Going in the garbage.

After feeding my cats Science Diet for many years, I bought a bag of the New & Improved formula of Active Longevity cat food in early January. It made them extremely ill: they vomited several times, acted lethargic and aloof for several days after. After this they would not touch the food anymore. I finally had to get a completely different brand of cat food, and they ate this and started acting like themselves again. I ended up throwing away the entire bag of Science Diet because I am convinced something in the New Formula made them sick. I would advise pet owners to stay away from Science Diet food!

Started Pearl, a red cattle dog, on Jd for mobility problems but noticed that she began groaning when sitting, panting heavily & had a lot of staining around her mouth. The vet thinks she has either Cushing's disease or a liver problem, but tests are inconclusive. I think the only change has been the food. Has anyone else had these symptoms in their dog?

We lost our 3 year old kitty this past Saturday. She died of Kidney failure and our vet thought she had somehow been exposed to poison. We have searched our house completely and were stumped on how she could have been poisoned. My husband remarked this morning about her cat food. I decided to research and found this site. We purchased the new and improved adult light formula just 2 weeks ago. I am sick thinking this food may have killed our Allie!

We have been using Science Diet dry food for over 5 years with no problems but within the last two-three month the dogs have been sick at least three times. Each time we took them off their kibble and put them on a mild soft food. Each time they got better then they got sick again as soon as we started to reintroduce their Science Diet kibble. Symptoms include vomiting, diarrhea, bloody stool. Vet gave them meds to sooth the stomach but it did not work. What did work was to take them off the Science Diet kibble. We are finished with Science Diet forever. There is something wrong with this food.

We adopted Omalley when he was 3 and half years old. He was a beautiful cat and all his own animal. The vet we go to said he needed special food because he was a stray and we agreed to Hills cd cat food. He did not like it and would scratch the floor around his dish. Sooner but probably later, he would eat it. After awhile he started throwing up. We thought maybe he was getting into something down in our basement. The throwing up got worse and when he was 8 years old, he passed away. How sad we were. I believe the Hills cd cat food was the underlying reason from what we observed and have been hearing about cat food. Our first cat Chiquita never had any problems until she was 22 years old and she ate Fancy Feast, canned. I tried Omalley on Iams for older cats and he liked it, but it was too late.

I wish that I had knew about this information before I opened the new bag of Hills Science Diet dog food. I thought that it was the Hills Science Diet Fruity Snacks because that was the only thing new in his diet. But I had also purchased a new bag of Hills Science Diet dog food and he wouldn't eat it so I hand fed it to him. Only if I had known I was killing my Buddy Ray. He finally stopped eating and drinking water, became lethargic, throwing up, drooling, diarrhea and then had clear blood from his rectum. He couldn't even stand up or walk. I started giving him water by syringe and pureed food in blender and put into syringe. I couldn't figure out why he got so sickly so fast because the only thing that I changed in his diet was HSD Fruity Snacks. I never dreamed that the new bag of dog food did it because he had been eating that brand for about 9 months and gobbled it up. I am so sadden with grief and despair at myself for hand feeding Buddy Ray this food that was killing him and finally did. I hope that no one else lose their beloved companion and best friend. I love and miss you Buddy Ray. <3 <3 <3

I was going to wait until I had more information but it seems like the word needs to get out! We recently lost our 4 year old cat due to what we strongly believe was the new formula of the Science Diet Adult Light cat food. He had always eaten this food with no problem. The last bag we purchased was the "new and improved formula". About two weeks after he started it he became very sick. Lethargic, diarrhea, stopped eating, in pain and hanging out in his cat litter box. We took him to the vet who ran many tests and they could not find anything. They sent us home and told us to feed him anything just to get him eating again. Went and bought a variety of foods that he immediately started eating and within a week he was completely better and back to normal.

We have two five-year old cats that have been fed Hill's Science Diet almost exclusively since they were adopted as kittens. About two weeks ago, we bought a new large bag of the Adult Light variety they have been eating for four years. We noticed it looked a little darker and greasier - the "new and improved" formula -- but didn't think much of it. Within a few days, both cats were "off" their usual eating routines, not coming to eat immediately and not cleaning out the bowl. One of my furry girls has a susceptibility to kidney problems already, but had been active with a good appetite and otherwise healthy. Within a week on the new food, she was lethargic and dehydrated. I took her to the vet and her kidneys are suddenly failing rapidly. While I know there was previous damage to her kidneys, the rapid onset of symptoms seems odd, and corresponds with the change in food. And the second cat, who has always been completely healthy, seems lethargic, isn't eating much and has been throwing up more than usual (vet visit by the end of the week if she doesn't seem better). I strongly suspect something is wrong with the food, as that is the only variable in their diet, exposures and routines over the past few weeks (they are 100% indoor cats).

I raised my 7 year old tabby on Science Diet. He loved it and from what I was told it was one of the best foods for him. WAS being the key word. I bought a bag of the new formula because that's all the stores had. Figuring SD knows how picky cats are I trusted their experience. I didn't think anything of it until my cat won't eat any of it. I noticed that the food looked different. I went back to 2 pet stores asking if they had any other complaints or recalls. Of course that was like talking to the wall.

I was going to change my dog food for my Great Dane and introduced a small amount of Science Diet to his regular food in the evening. The next morning, he was bloated and dry heaving. I took him to the vet where it was verified that it was bloat and emergency surgery was done. Afterwards, dr told me surgery went well but his heart was having troubles from the stress and he later died. He hadn't run around or done any of the typical things that can cause bloat before or after eating the night before. Only had some of that food.

I have raised my 6 yr old tabby on Science Diet; however, in November 2013, I bought their newly improved cat food. Within a week or two, my cat started throwing up every other day. Then every time he ate. He's lost 25% of his weight. Quit eating, became dehydrated. Was admitted to hospital, IV's, testing, etc. We can not find anything causing his ill. Came home with ID prescription cat food. He became healthy and quit throwing up. Put him back on Science Diet. Throwing up all over again. Bought some more ID cat food. Not throwing up anymore.

My cat suddenly became very sick having daily seizures, vomiting several times a day, and episodes where her back legs were not working because her kidneys were shutting down. I really thought she was going to die. She had eaten Science Diet all her life, but it was when I bought a new bag in Nov 2013 that said "new improved formula" that she quickly became very sick. Then I found this site and other sites where so many dog & cat owners are linking their pet's illnesses to the new formula of Science Diet. I immediately took her food away and went out to buy another brand. She was better right away, no vomiting or seizures since and it's been a few weeks now. I really believe if I hadn't found this information and changed her food when I did my cat would have died. Please pass this on to every pet owner you know, Tweet or Facebook it to get the word out about this. Science Diet should recall this product but they won't do it until there is an uprising.

I really wish I had found this site earlier this year. Our cats have been on Sd hair ball control for years. Our 5 yr old tabby out of the blue started becoming lethargic, throwing up foam, going into the litter box and just crying. These are indoor pampered cats! Took him to the vets. They gave him IV fluids and kept him over night. Tests showed he was blocking up with urine and his kidneys were failing. They unblocked him and he stayed that way overnight. We were going to bring him home the next day but sadly got a call he was reblocking. The Dr said there was surgery but more than likely this would keep happening. We made the very painful decision to have him put down - he was suffering so much. Now reading all these comments I have no doubt SD killed our cat!! Our 7yo girl cat gags a lot. I'm curious to see if that stops with changing her food. Just bought a new bag yesterday. I'm trashing it and heading to the store right now.

I have been feeding this to my dogs for approx 2 1/2 months as it is what my Vet sells (at a ridiculous amount btw, $30.00 for an 8 lb bag). He insisted this was the best food on the market. I found it cheaper on Amazon and the dogs were fine for about 2 months, but the last two weeks they have both been vomiting about every other day. We finally have through trial and error figured out it was the food.

I have had my tux. cat since he was 2 1/2 mos. old. Always gave him Science Diet. August 13, 2013, I went to work and when I came home, my tux. was lethargic, drooling and foaming. Took him to the vet and they gave him a shot of vitamins. That was at 4pm. By 5:00am, he was dead. Really didn't think nothing of it. Oct 11, 2013, we adopted 2 kittens, litter mates. They were on a Purina kitten food and Science Diet kitten mix to switch them to Science Diet. On November 5, I started a Science Diet kitten and Science Diet adult (same bag as the tux had) mix. Getting ready for work on the morning of the 6th, Joker (6 mos old) started vomiting and howling in pain. From 5:30 am until 8am, he vomited 5 times.

When the ingredients say chicken meal that is NOT beaks, feathers etc. Regulations state that Meat meal is "exclusive of feathers, heads, feet and entrails." It's boiled and then died and ground. It's similar to the meat left over when soup stock is made. When your food says chicken BY-PRODUCT then you are then getting all of the hot dog parts PLUS heads, feet, beaks and FEATHERS. Also, since ingredients are listed in order of weight having a "dry meat" listed early means that a larger portion of the final product is/was meat and not fillers.

At the insistence of our vet, I put our 10-month old cat on Hill's Science Diet. She was perfectly healthy, happy and the joy of our lives. She refused to eat the Science Diet. It was NOT labeled Improved. It's the "Grain Free." Within days of nibbling at very small amounts of these pellets, she became lethargic. The vet said she had a temp of 105 degrees and a bacterial infection. She is strictly an indoor cat. Never goes outside and never associates with other animals. She is now on intravenous, in severe pain, and the bill is at $2,000. But it is the heartache of knowing I fed her this stuff. I insisted she eat it because the vet said it was the right thing to do. This company needs a thorough investigation now before any more animals suffer.

After using Science Diet Adult Small Bites for over two years, we brought home a bag last week, noticed it said improved, figuring that since it was now Velcro closure, as the 'improved' fed our two POMERANIANs. Within three days, both started gagging food, later vomiting. By fourth day, bloody stools began by the next morning. I had to beg people to help me with money to get them to a vet! I am on SSD, no money until the 3rd of each month. This was the day after Thanksgiving 2013! I almost had a heart attack when my precious BUFFY spewed blood from her rectum! Little Diablo then did too. By this time, they were beyond weak. All I could do was pray!

Please BEWARE of this food and read the ingredients. My vet recommended this food for our Basenji when he came down with stones in his urine (it is Hills U/D food)....Not knowing any better and trusting our vet, we gave it to him. A while later, his liver enzymes went through the roof and he was diagnosed with Liver Cancer. Later on, I read the ingredients in this food. It begins with water, cornstarch etc etc..... I later found out that all corn now is GMO (genetically modified)........ In retrospect, I would have rather had my pet come down with stones again than have to feed him this food. Doctors only take 1 course in Medical School on Nutrition. PLEASE read the ingredients before you purchase food for your pet..... BTW, if the first ingredient says chicken or turkey MEAL pass on it....... Meal can mean anything from bones to beaks.... I hope this helps someone.

My Boston has been on SD since he was a puppy - he's now 6.5 years old. Petco was out of stock of Science Diet Adult Light Small Bites Dry for about a month or so in the two stores I frequent the New Orleans metro area. I bought the large bites instead. I noticed he would let the large bites sit for hours instead of normally gobbling down his food right away. Now, he's back on the small bites and will not touch it.

I have been feeding Science Diet cat food since my cat was young and he is now 15 years old. I was made aware that when they did an ingredient change last year, to slowly introduce the new formula food with my old bag because the formula has changed. My cat has never had extra vet visits besides his annual ones. I am completely satisfied with this food. Thank You.

I've had my female Pug on Science Diet Light Small Bites for almost 6 years. Recently, after their formula change, she became violently ill. She would vomit every time she ate. She would eat her treats, but wouldn't touch the Science Diet food after a few weeks of her eating patterns getting less and less consistent. I just changed her food and now she's fine! There are so many other reports of this happening, I think it's outrageous that nobody is saying anything. I called the company and they offered me coupons... REALLY???!!!! What idiots. I will be writing letters to other companies and news outlets to expose this disaster. Switch your food immediately if you know what's best for your pet!

My Afghan hounds almost died. I posted an entry I think it's #124, early 2013, Virginia Beach, VA. Just want to say I put them on to Acana then Orijen. They have eaten the brand since they fell ill on the Science Diet new formula. The change in food helped them recover. I have not seen any problems with them in stomach or stool in almost a year. The older dog also has seen coat itch stop and has his hair filling in on the ridges of his tail and tip of nose. He is 9. I am surprised and pleased. The Science Diet was garbage in my opinion and I am glad my dogs are alive. Orijen seems to do well for me though recommendations are seldom taken in by others. I know it is expensive but I would rather not bury my animals this week. Try a different food. It really might help your animal.

My 13 year old dog has been on Science Diet I/D for the past 3-4 yrs and recently she has been hacking. At first when I noticed this, she was grooming herself and thought nothing of it. After a little time passed, I would see her hack again, but noticed she was not grooming herself. I was concerned, so I took her to my Vet who I've used for the past 27 years. After x-rays and ultra sounds, she was diagnosed with an enlarged heart chamber. This after dealing with liver enzymes levels increasing over the years (approximately same time period) I was horrified! I took her off the Science Diet I/D and put her on a limited ingredient diet and liver enzymes which were at 1600 dropped to 800. (200) is considered normal. This and adding heart medication was the only changes I made to her routine. My vets all agree the heart meds wouldn't have lowered her levels. I would STRONGLY ENCOURAGE anyone using Science Diet to stop using it as your pets health is at stake!!

In the last few cases of Mature Adult Gourmet Canned Turkey Science Diet, there was a 1/4" air space along one side of canned food. The exposed edge of the food was much darker in color. I am concerned about this since over the 10 years I have used this product, there has never been a problem. Anyone else have this problem? The manager of the store did not run into this before (I opened 2 of 4 cans). Could there be a problem with the canning process that allows air in the can?

Science Diet Indoor Cat Dry - Hills changed this food this year and the result is horrible. My cats still hate it and do not eat a lot of it. Also, their bowel movements have been terrible since eating this food. I am in the process of changing them to another brand.

Unfortunately I found this page before I lost my beloved Manny. We have used Science Diet for 10 yrs for our "children". On this particular occasion they were out of our normal bag so we purchased this one. New and Improved??? Within a day our pets became ill, but we didn't know what could be wrong. They all were very lethargic and experiencing diarrhea. One of the ones not acting right refused to eat and we thought perhaps he just didn't feel well. So the next night when we tried to feed him he again refused it, by 2 a.m. that morning he was gone. We finally thought of the new dog food and went and purchased the old bag, the one we had always used and within days everyone was back to somewhat normal.

Took my dog for a check up. Changed her food to Science Diet. Several months later, she passed away from cancer.

Took in a stray many years ago. Fed her Science Diet from the start. Hairball Control. Recently, decided to change to the mature version of same food. Cat lost weight, went through bouts of diarrhea and vomiting. I bought a small bag of the "old" food and things have righted themselves. Gaining weight back and no vomiting. Will find another food that suits her if Hill's is producing products that sicken pets. Appreciate the info here on this site.

I have been feeding my cats Science Diet for over 25 years. They have always been healthy and happy. This recent change in formula to the Science Diet Hairball Light formula has caused my cats (12 yo) and (3 yo) to howl in pain, vomit, and have very hard stool. It is a shame that they changed the formula so drastically that the many animals are in distress. My 12 year old white cat almost stopped eating completely. Fortunately, I had been watching his behavior to see if he would adjust to the new formula. I tried the Hairball light and Mature indoor formula as I had to give him a low calorie food for weight loss. Both formulas caused them distress, the Mature one they just stopped eating. They were down to 1/2 can of light wet food for the both. I spoke to my sister a vet tech and she said take them off before they get sicker. I had tried Nutro in the past but it was so rich it cause them to have loose stool. I switched them to Nutro Max Intro Weight control and miraculously my 12 year old cat appetite is back. Day 3 he had vomiting and stinky stool but ever since they have both been happy and active again. It seems to be helping with chin acne too! TRY NUTRO MAX INDOOR WEIGHT CONTROL.

My miniature schnauzer just turned 8 years old. Due to the advice of our vet, she has been eating Hills Science Diet, w/d food for a couple of years now. Within the past two years she has had several health issues. First she became lethargic, started vomiting, (couldn't even keep down water) and had bloody diarrhea. We had to take her to the vet. At that time, he insisted we change the food she was on then, to the d/d because he thought it would do her the most good as he thought she had food allergies. He also diagnosed her with pancreatitis. She stayed with the vet for a few days getting some IV fluids. We picked her up and took her back home and fed her the d/d. She never really returned to her old self. Then one day I noticed that she couldn't see her toy when I threw it. I took her back to the vet and she was diagnosed as blind. I mean it was basically overnight! She was only 7 years old then. He told us there was no cure.

This week I took my 12 lb rescue dog to the vet for bloody diarrhea and vomiting. His liver enzymes were very high. He has been eating Hills Science Diet for Small Breeds for about 6 months now! I am so angry and sad after I read the other reviews here. I thought I was buying a good quality food for my little guy! He won't eat it anymore!

I am wondering what dog and cat food to feed to my animals. I have fed SD for over 30years. My neighbor has lots of dogs and twice she's tried to feed SD and her dogs have bloody diarrhea and are throwing up. Then another friend of hers lost two very healthy puppies after within 2 weeks feeding SD. The vet checked and they had intestinal stress. I love my dogs (all around age 10) and my cats (both about 3) and I don't want to lose them. Anyone have any suggestions? I think I have been blessed so far and haven't gotten any of the new formula. My neighbor and I compared food and they are different shades. She must have the new formula. I feel like I'm playing Russian roulette with SD. Help!!

Our seven-year-old dog was having problems urinating so we ran some blood work and did a urinalysis. In our otherwise healthy male dog bladder crystals had formed. The veterinarian prescribed him Science Diet U/d to help with the formation of the crystals. About two weeks later, he was vomiting blood and had bloody stool and was lethargic. Took him to vet and after all kinds of tests it came back; his liver count was in the two thousands!! It's supposed to be in the two hundreds! Also the bladder crystals and vomiting blood had no relation. The vet's office seemed to think my dog had eaten something he shouldn't have. Which this is possible but really impossible for we are very aware of what's around. Our pets only eat pet food.

My Lab Tess was only 5 years old when we lost her. A year before that I put her on the Science Diet Diet plan that for some reason was only out for less than a year. It came with the bone snacks as fillers. She lost 21 pounds in a year. My vet was very happy with her weight. Shortly after she started this diet she started vomiting uncontrollably to the point it would take an hour or more comforting her to get it to stop. We were taking her to the vet and they were treating her for reverse sneezing and later, a gastric infection.

I have three cats who have been eating Science Diet since I adopted/rescued them (the one I've had the longest has been eating it for 8 years). I've always felt very proud that I am able to provide my cats with a top-notch food purchased directly from the vet. But I recently brought home a bag of C/D formula and they absolutely refuse to eat it. They hover their bowls and sniff as if there's something foul-smelling in them - then they back away from the bowls. I've tried the "They'll-eat-when-they're-hungry" tactic but it's been over a day and they're still not eating, so I have to go find a suitable replacement food today.

I have two cats and I started feeding them the SD new formula of Light Diet. My older cat started to vomit the food after a couple of days. It seemed like he was not chewing the food since the pieces are small. We switched them to SD Hairball Control Light and the same thing happened with the older one. He then stopped eating all together and began vomiting liquid. We took him to the vet this morning and they couldn't find anything wrong with him. I took him off the SD and switched back to Royal Canine. This evening my little one started vomiting the SD. I will never buy SD again. :(

I have fostered for a rescue for 4 years now and they always use SD. I am an office manager for a local vet and we have recommended SD for the last 15 years. I have been employed at the clinic, without issue. Earlier today, I was very upset. I have 4 cages with kittens I am fostering totaling 17 kittens. ALL are on SD. I opened a new bag the beginning of the week and noticed instead of the kittens eating it, they were spilling it on the bottom of the cages and crying at me. It has been 5 days and I thought something was seriously wrong with the kittens. They were ALL losing weight, had loose stool, some were vomiting and they were very thirsty. I was/am very concerned about them and decided to try a different food. Purina Kitten was what I brought home. I was shocked when I tried to put it in the first cage. The kittens rushed to the bowl and one bit down on my pinkie; he wanted the food so bad. I am pissed. It was the same result with ALL the kittens.

Our dog became sick and weak. Took him to vet. $500.00 later, they really found nothing. Gave him antibiotic, etc. I stopped feeding him his Science Diet Large breed mature adult dog food and he is getting back to normal. Just bought a bag of Science Diet, but he is not going to eat any more of it.

I have used SD for a very long time, 5 or longer years and I have many cats. I didn't have a problem until they went to the New and Improved formula. One of my cats, 5 yrs. old and overweight, became sick within days and had exploratory surgery and they could not find anything. Did x-rays. Spent mega bucks - $800.00. The cat was vomiting liquid for 3 days and was constipated. He would cry and vomit the food up.

A month after switching my cats to Science Diet, my 12-year old cat started vomiting, having mucus in her stools, eventually stopped eating, became lethargic, and started symptoms for a dying cat like hiding. I took her to the vet and her liver enzyme count was through the roof. She eventually passed away three days after her vet appointment, which involved her staying there for three days with pain meds, anti-nausea meds, IV Fluids and something to calm her liver. I'm not saying it was the food, but now, my 13-year old cat is having the same symptoms. I just hope it's not too late!

My 8-yr-old cat has been happily eating Science Diet her whole life. We went from Kitten formula to Adult Indoor to Hairball formula, without complaint. Last Sunday, I opened a new bag of food for her and noticed by Monday evening that she had only eaten a few pieces. Yet, she was devouring her daily ration of tuna. I knew immediately there was something wrong with her food. At that point, I noticed the "New Improved Formula" on the label, I brought the bag back to the pet store and thankfully they had a few bags of the original formula still in stock, I brought it home and kitty devoured it instantly. Now I guess I'll have to find a new pet food NOT made by Hill's. After having read the various reviews on this site, I cannot believe how lucky I was that my cat refused this food altogether. I am so sorry for those pet owners who have had such terrible experiences. Hill's is well on its way to ruining its good reputation and it would appear they've lost many customers already.

I have fed my 4 cats SD Original formula for years, and they loved it, but I ran out and the store was out of stock. I bought SD Active Longevity. My biggest eater got sick within days. He could not eat or drink anything and vomited liquid for two days until I took him to the vet for x-rays and blood work, shots and hydration (>$500). He recovered and the vet could find nothing wrong. I put the Active Longevity in the drawer and bought the newly stocked SD Original formula. It smells awful, just like the other "New and Improved Flavor." The cats don't like it. Both bags say 100% guaranteed on the front, so while I was going to pitch them in the trash, I will probably take them back to the store so it becomes clear to the manufacturer that there is a problem. Too late for me as a customer. I won't buy this again!

I've been feeding my 7-year-old cat Science Diet Adult Light cat food for years. I bought a large bag a couple weeks ago and the first thing I noticed was it seemed to have a different texture and a really horrible smell. After eating it, my cat started having really runny stools. I didn't even notice the "New and Improved Formula" label until I looked at the bag more closely. Fortunately, she's not been throwing up, but I'll never feed her this stuff again. What really irritates me is that I intentionally used to buy Science Diet because they claimed it was healthier than the cheaper food on the market.

I decided a few weeks ago to switch my cats' food to something that I thought was going to be good for them but instead I've noticed all 3 of my cats vomiting after they eat. I have healthy cats so I decided to do research and I found this site. I cannot wait to get home and get rid of that food. I'm out about $40 b/c of the large bag I bought but I would rather have my babies.

I recently bought my dog Science Diet Mature Adult Active longevity "new and improved formula" dry dog food. He has experienced uncontrollable symptoms of diarrhea, gas and vomiting!! He has been on this type of food for a couple of years and this new formula isn't right! He couldn't hold down WATER! This new formula left me with a sick dog and an expensive vet bill! I will not be buying this type again!

I have 3 rescue cats (7 years, 5 years and a brand new one 6 years old). I have fed them SD since they were kittens. Now the new cat started having diarrhea, lethargic, runny nose and sneezing. Everything checked out OK at vet. She said she might be stressed out. Now my 5-year-old is sick. After reading this, I threw out the new and improved SD. They have all been throwing up. I noticed a strong smell with this new bag. I just opened it maybe 7 days ago. They were all eating it. I knew something was wrong with the strong smell. Need new food. Help!

After reading these reviews, I have to wonder if that isn't what is going on with my cats. I had fed a different brand for 2 years, but then switched to Adult Indoor Science Diet. The cats (I have 3 rescues) loved it and had no problems until the last BIG bag I purchased. Within a few weeks, one of my cats started vomiting and started losing weight. The other two seemed okay but would not eat as much. I kept on feeding them the SD, thinking they were stressed due to a move I was making. When the first cat became very thin, I took her to the vet. She has an early kidney failure! I started feeding her a special diet and she is doing well. I kept feeding the other two the SD, not making any connection to the food. Finally, when the two started acting sick, I took away all SD and switched to a new brand. Now they are fine! No more SD for us!

My 5 year old kitty is in the hospital fighting for her life from this new food. After checking the bag of food I bought last week, I too noticed the "New and Improved" label, and that it doesn't smell "good" like it used to. Come to think of it, the last bag said that as well. And like many others here, my cat was vomiting whole pieces of this new food occasionally for weeks before finally refusing to eat. Only after finding this page have I become fully aware of this situation. I am a very busy waiter who will spread the bad word about SD to every person I meet - you will pay for the countless animal deaths on your hands SD.

My 14-year-old cat has been on WD dry food since she was adopted. That's all she will eat. In the last couple of months, she has lost weight and throws up whole food (not chewing it) often. She's very hungry and the vet says her teeth/gums are good, so I watched her closely and determined she was just licking her food. To help her eat it, I tried to smash up the kibbles. They are hard as rocks! I had to use a heavy rubber mallet on a cement floor to break them! No wonder she can't chew them. Problem now is what can I get her to eat? Any suggestions are welcome.

We've had our rescue cat for a couple months now, and from vet recommendation purchased Science Diet food. Our cat loved the small bag we bought, so once it ran out, we picked up a large bag of "improved formula". Almost overnight she became lazy, uninterested in playing, and soon uninterested in her food. We fed her some random cans of food we got as samples in the mail (Sheba) - she devoured the food almost instantly. After ONE google search, and finding this review page, I threw the Science Diet in the trash and ran to the store to find another solution.

I was given a prescription for R/D from my Vet for my overweight kitty. 3 different bags made her EXTREMELY ill, vomiting, lethargic and she almost died. Replaced the Science Diet R/D crap with a different brand entirely and kitty recovered QUICKLY!!! HILL'S SCIENCE DIET IS A CARCINOGENIC, POISON-FILLED CRAP PRODUCT!!!

I also bought a big bag of the Science Diet Adult cat food, as I do every month, for my 2 cats (littermates) who have been eating the same food for 10 years since they were kittens. They refused to eat the new formula and have starved themselves for 3 days. I frantically drove around to local pet food stores and found one last small bag of the old formula, which they chowed on today. I have no idea what to do. They don't like any other foods. At least I have this last bag to work from to try to transition them. But to what? I am very interested to know if anyone has found a new food of any brand to transition to.

I have already posted on this site a couple of times about my similar story that many of you are now facing - cat healthy and only eating original SD for years, eats new formula, starts vomiting, stops eating altogether. Sadly after trying everything to heal her, including a surgical feeding tube and $2,700 in pet bills, I lost my battle to save her this weekend. Whether it's this food, or any other, please don't let your pets vomit more than a couple of times before seeking treatment. Even vomiting/stopping eating for as little as three days can lead to a downward spiral towards "fatty liver disease" that's hard to reverse. It's heartbreaking. Thank you for the link to the FDA. I filed my report today.

In my post on May 25th, the link to the website I found was not included. I'm not sure if this one will be posted or not... but just in case, the site is fda.gov. It is the website for the FDA and there is a section there where you can specifically file pet food complaints. (I had originally tried to include the link that would take you directly to that part of the site, but if you can at least get to the FDA site, you should be able to find it.) As I meant to say, my heart goes out (not my hearts go out...I only have one!) to all of you and your pets. I believe that if we each take a stand against this faulty food, maybe we can help others that may not have connected the dots yet to realize that the "new and improved" food formula from Hills Science Diet is what's causing their pet's problem. Thank you!

I am so saddened to read all of these complaints. My two cats have been eating the Science Diet Adult Indoor Cat dry food formula for over 4 years (and ate the kitten formula before that). Both started throwing up from the "new and improved formula", one right away and one a few weeks later. The one who threw up right away almost never throws up. They're both almost 5 and I can count on one hand the number of times she has ever been sick. The other one throws up some monster hairballs, but usually every few months at the most. Now, he has been throwing up for a week. On Sunday, he threw up five times, twice with food in it and three times just liquid. After a few good days, I came home tonight, fed them their dinner and within 20 minutes, he threw it all up.

An internet search appears to indicate that Science Diet acquired/filed a patent in late 2012 for using or adding propylene (plastic?) to improve pet food shelf life. Could this be the crystal coating on the kibble/food someone else mentioned in a post? Is this material causing varied problems, organ damage and kidney stones (propylene stones)? Does New and Improved means new and improved shelf life? But at what cost? I hope someone investigates for the public good.

My dogs (5) have eaten SD most of their lives. Within two weeks of feeding their new and improved formula, I had two sick dogs. My five pound toy poodle came very close to dying. She was bleeding profusely from her behind. After all the testing and four day stay at the vets, the conclusion was that she ate something. The only thing that she ate was her dog food. I contacted Hill's, and they responded very quickly with a 2-page questionnaire that they wanted me to fill out along with a "Here’s a coupon for your trouble”. I filled out all the information they asked for about both dogs that were sick and emailed it back. This was over a month ago. I have yet to hear anything back from them. I’ve emailed them twice. With that coupon, I bought their cat food; which my cats have also eaten before without any issues. Within hours of them eating the food, all four cats puked. That bag went in the trash. I wouldn’t even feed it to our local wildlife. I’m still holding on to the dog food, just in case they want it for testing; but as a once firm believer in SD products, I will never ever feed their products again.

I bought Science Diet Mature 6+ for my Lab last week. She has eaten it since 6 years old (she's now 11). But now, she was slow to eat it and had to be encouraged to eat it. This morning, I just tossed the uneaten portion back in with the rest. Then, the same thing happened tonight. She didn't want to eat it. A Lab not eating her food is extremely rare and unheard of. The lack of eating prompted me to smell her food. It smells horrible (sort of burnt-smelling). I then looked at the package and saw it was "New and Improved". We started feeding her another food tonight and will investigate further tomorrow. I glanced at the package but didn't see any lot stamping for tracking. I'm now concerned for her health in light of what I've read online. I'm also concerned about when this new dog food hit the market/store shelves and how many animals will be affected.

On 5/15/13, I had 3 Pomeranians, 9 yrs (5 lbs), 11 yrs (5 lbs) and 13 yrs (10 lbs). Sadly, having no choice but to have a house call vet take him to his resting place, I had to say good-bye to my 11-yr-old baby yesterday. I'm just going to state the facts we have right now as the situation at hand is evolving into a nightmare, one I hope others may be able to avoid.

We've had our cats for seven years - all three are rescue cats. They have all eaten Science Diet their entire time at the shelter and then with us. I bought a bag of the kind we always got a week ago. I noticed it had a different design on the bag and has the label "New and Improved". I got it home and noticed it was a bit of a different color and horrible smelling. Since that time, two of my three have suffered a food allergy, and all three will hardly eat it. When before they would clear out their bowls, now food is being left in it and they have no interest in it at all! I'm not happy at all with the vet bills, plus expensive specialized cat food (which two will eat but one won't look at) and unhappy cats due to "New and Improved" food. Now I have to hope and pray I can find something they'll eat before I lose them!

While trying to remedy my cat's vomiting and then subsequent non-eating/lethargy issues, and after bloodwork tests that came back ok from the vet, my family and I started looking more closely at the before and after "new and improved" Science Diet Adult Light dry cat formula that she's been eating exclusively. We noticed that wheat gluten has been added to the new formula - it doesn't appear to be in the old formula (Corn gluten meal is different). From what I have read online, wheat gluten can possibly be an allergenic in some cats and dogs, causing digestive and skin issues. I'm not a vet. I'm just doing my own research online like the rest of this forum, but thought I would share this as just one possibility for my cats recent ailments. I personally will be switching her to a wheat gluten-free formula in the hopes that it helps her.

My cat has eaten Hill's SD Indoor Cat Adult Formula for nine years. When we ran out of the last bag, I bought a new one only to discover upon opening that the formula had been changed. I compared the ingredients. The fat content was much higher and the fiber content lower. Cats need to gradually adjust to new food. It has to be phased in and mixed with the old little by little. I didn't have any of the old left and my poor kitty started vomiting. It's been five days and she regurgitates or vomits every time she eats. I've tried giving her smaller, more frequent meals, adding water and canned pumpkin to her dry food. We'll see if it helps, but I found this site because I noticed that others' cats are having the same symptoms, which has me quite worried. Something is rotten in the state of Hill's. I'd also love to know what brand I should switch to now that Hill's has lost my confidence.

My cats have also been on Science Diet all their lives and are now throwing up. I was looking at the list of ingredients and found that they have added chicken, not chicken by-product. This could be the problem. I'm taking one to the vet tomorrow and see what they have to say. This sudden change to meat food could be the problem.

My cat has eaten this food exclusively the past 4 years. She has always been very healthy and is strictly an indoor cat. The past week, she started vomiting which is unusual for her. A $200 vet bill showed perfect health/blood work. I just pulled out her food and noticed the new and improved formula. I can only attribute the vomiting to this new formula. Probably making my baby sick, stressing her out at the vet and causing me a lot of worry. Not to mention the hefty bill.

My cats have been on the Science Diet food since they were kittens. They are now 3 and this new formula they are not eating. Seeing all these people's complaints makes me wonder if Science Diet plans on going back to old formula. I won't be buying the new formula food anymore. Does anyone have any suggestions as to what kind of food they switched to?

We bought the new Adult Indoor formula and it made our cats sick. They've been on SD for years without problems but the sudden switch has really messed them up. It's common knowledge that cats can't switch foods abruptly, but SD changed their formula without warning. Now, our cats vomit every day and one has stopped eating all together. We're very upset!

I have three cats that have used the Mature Cat Hairball formula for years and it had greatly reduced the amount of hairballs, as one might expect. A few weeks ago, we purchased a bag of the new formula and I have had cats puking every day since then - not hairballs, just large amounts of puke. My cats are obviously losing weight and I will have to find an alternative to this once good product. I would have rated the previous formulation with four stars, but now I give it a one.

I purchased Science Diet a couple of weeks ago. My pet was fine at first but about a week after eating the diet, she began to vomit. I cannot believe the sales woman for Science Diet would even recommend this food to anyone with these reviews. I wish I would have read them first. My pet had an overnight stay at the vet and a $200 bill.

We have a busy house with three kids, 2 dogs and 2 cats. We just had to put our beloved 12 year old cat down. He stopped eating about 2 weeks ago. He's always been overweight and consumed everything he could get his paws on, therefore always on a diet. He was fed different Science Diets over the years. We thought the eating issue was just him slowing down due to age. And our two dogs sometimes would eat any cat food that wasn't consumed so I don't think I realized how much he wasn't eating.

Science Diet recently changed their Indoor Cat Formula. My cat has only had this her entire life. No treats, no other food. She refuses. Now that the formula changed recently, she throws up 10 times a day. I don't know what to do but changing the diet of all these cats was not a good move. It's not new and improved. It's new and worsened. You're killing my cat.

I have purchased Science Diet for years. I purchased the new and improved formula. My dog was throwing it up right after eating it. I almost lost my Lab due to infection. He was dehydrated. 500 dollars later, X-rays, fluids, blood work etc., I was spoon feeding him. He was too weak to walk. Please do not use this food, ever! He is still recovering. Shame on Science Diet, a once trusted source!

New advanced fitness lamb and rice - Both dogs loved the old formula. They are 4 1/2 years old and have always been on Science Diet. Last purchase is "new" formula and they both sniff and walk away. One dog has Addison's disease; the other is good health-wise. However, the healthy dog eats grass and vomits shortly after eating. To get them to eat I have added a little chicken broth. I am so disappointed in Science Diet - all was fine. Not sure what brand to try. This is so important for my Addison dog, as she can go into crisis easily, especially if food is not working for her.

I have fed my Afghan male this food for years. After his getting ill last month and then again yesterday, I thought hard. His food smelled a bit stronger than usual. It also looked like it had salt all over the outside of the kibble (?) not meal! It was salt crystal like stuff! My female that I started on it 3 months ago is too sick. After noticing the large amount of unprocessed grain in his vomit, I became very suspicious and mad. I looked it up and found all of you. It's the exact same story especially the bad smelling gas. It has been 8 yrs and never have I smelled that. Gosh, who knows how many have not figured it out? Salvador is very weak. I hope he pulls through this fine. I wouldn't have known if it were not for all of you speaking up. Thank you with love.

Science Diet Sensitive Stomach - My Shih Tzu/Maltese mix has been on this formula for years due to stomach issues. Recently I purchased a bag and noticed it says "New and Improved". She has since started vomiting. I will not be purchasing your products anymore. Why change something that so many pets were just fine on? That's just sad! Shame on you, Hills. Look past your $$ signs and see what's important.

Our Corgi has been on Science Diet Light for three years without a single problem. When her dog food ran out, I purchased another bag as I always do. I noticed that the new bag of food pellets were lighter in color than her previous bag but thought nothing of it since I had been giving her this same food for over three years. Well, within 24 hours, she began to vomit and have uncontrolled diarrhea. She was lethargic and would not eat. I thought maybe she had picked something up on one of our walks, ate it and it made her sick. I took her off the Science Diet and gave her boiled chicken breast and rice to get her digestive system back on track. It took over a week before she began to feel a little better.

Our dog would throw up immediately after eating her food. It started when we bought her a new bag of Science Diet Sensitive Skin dog food, but we never really put two and two together since we had always fed her this food. There have been times when she has gone to our in-laws and ate a different brand of food and other times, when we got free samples of other food in the mail that we have given to her with no issues. Since she has eaten all different kinds of dog foods with no issues and was never sensitive to us changing her food, we thought something was wrong with her.

My cats were on Royal Canin SO and it caused severe constipation and dry skin. I switched both my cats to Hill's c/d Multicare, and both issues have started to clear! My cat's UTI is in check. This food is amazing!

I am appalled at what I have found on your site about Science Diet pet food. We rescued a 4-month old puppy from the local APL two and a half months ago. He is 6.5 months now and has proven to be an excellent companion for all of us in the home. The APL and the caring vet recommended Science Diet food for the little guy which we continued to buy for him. However, like the reviews I found here, he started to experience severe diarrhea three days ago. Just by chance, we had just bought a new bag of Science Diet the day before that, and I have since connected the dots.

We have used Science Diet Dry Canine ID Dog Food for our lab/setter mix for approximately 5 years. She has a touchy stomach but no diagnosed health issues. The last bag we bought had the "new look and formula" stamp on it. She is now throwing up after every meal and refusing to eat. We took her to the vet for many expensive tests and medications to get her stomach settled. There were no health problems, and the lab was normal. As soon as we started her back on the ID, the picky eating and vomiting resumed. I guess we are now looking for a new food. Please change your formula back, Hills!

British Yellow Lab (pure bred) had severe blistering around eyes and on top of snout. After the dog quit eating the food, the problem went away.

We have a 9-yr old Vizsla that has been on Science Diet for 8 yrs. In the last few years, we switched him to Science Diet Mature Adult Small Bites for less protein in his diet per the vet. He ate the food and seemed to be doing fine. Recently, we purchased another bag of food about two weeks ago that was marked: "New look and improved formula.” Now, our Vizsla has not been eating his food and we had to take him to the vet for blood work & urine analysis, which came back with him having problems with his kidneys. The vet said he may have kidney failure but not sure if it is acute or chronic. He is now on antibiotics and more tests to come afterwards. My husband & I are very angry and hope that he will be ok.

Science Diet Advanced Fitness Small Bites - I have been feeding this dog food for about 3 years with great results. Then for about a week, the store where I buy the food was out. Finally, they had some back on the shelf and I bought a bag. My 3 dogs about run me and my son out of a room. They all 3 have really bad gas from eating this batch of food. They are not given any scraps from the table, just their dog food. I have a small older terrier mix, a large lab/shepherd mix, and a boxer. The boxer is the youngest at almost 2 years. I have had him for about a year. The lab mix is 7 and the little terrier is 15. They all did exceptionally well on the food before, but the last bag says "New look and improved formula" on the bag. I'm afraid I am going to have to change brands. I'm not sure what the so-called "improvement" was, but it sure doesn't agree with my dogs' digestion systems!

I got a kitten from the animal shelter. They started her on Science Diet Kitten formula so I kept her on it. Everything was good. Shortly after she was a year old, I changed her to the Science Diet Adult Cat formula. With the first bag, she was okay. I then had trouble finding Science Diet Adult Cat. When it was back on the shelf, I purchased it. My cat immediately started throwing up. My daughter had the same problem with her cat. A neighbor was concerned because her cat had started throwing up. I asked what food she used. She also used Science Diet Adult Cat formula. I do not know what changes were made with your new formula, but I have taken it was not for the better. All three households have changed the brand we use. We have all changed to a different brand, and none of the cats is getting sick anymore.

I have been feeding my Miniature Pinscher Science Diet since he was a puppy and moved gradually to Mature Adult formula. Over the last two weeks, every time he has eaten the Science Diet, he throws up everywhere. I thought I had mistakenly bought the wrong formula and actually went out and bought another bag - same results. I did notice on the last bag a "New and Improved Formula" tag. I'm very disappointed and have to throw it away.

My dog is an Australian Shepherd and we have fed her Science Diet her whole life - she is six years old. Over the last six days, she has started vomiting every time she eats it. Last Thursday evening (December 27), she threw up her food immediately after eating most of it, but I chalked it up to a nervous tummy from spending the day at the groomer's. On Friday she did not touch her food, and on Saturday evening when she decided to eat the Science Diet, she threw it up immediately. Since it was after hours for her veterinarian clinic, I decided to cut off her Science Diet food for 24 hours and give her a couple of cups of cooked chicken and rice to see if her tummy had settled. She successfully ate my homemade chicken and rice dish for lunch and dinner on Sunday - no sickness, no issues.

I adopted a 2-year-old dog from a shelter. They recommended I feed him Science Diet. They also gave me a free #5 bag to go home with the dog. I began feeding it to him. He would mess in his cage while I was at work. I also gave him a Kong with peanut butter with a few treats. He continued to have bowel issues. I eliminated the peanut butter thinking that was the problem. His bowel problems continued. Every night, I cleaned up the mess and gave him a bath as well as laundry to be done. It has been two weeks with the same issues and until I found this site. I did call the shelter to inquire about any problems with Science Diet. They said no and I should contact the vet and keep feeding it to him. I purchased another brand with no grains in it. Time will tell. He has only one meal of the other brand. I feel bad that the poor dog had to suffer these issues due to so-called reputation of the company. The poor dog was not feeling well and trying to adjust to a new home. It is unfortunate that ignorance-is-bliss attitude continues with Science Diet. I won't be buying this dog food brand ever again.

I have been feeding my two cats Science Diet Lite Chicken Dry and Wet all their lives. One week ago, we took them to our cabin as we do every weekend. I feed them the wet and dry. She was finicky as usual so he polished off both of the wet food on Friday night and Saturday evening. She ate it Saturday night. Sunday, he had vomited, had diarrhea, and would not eat. She followed suit on Tuesday. Testing profiles are the same, though he is much more ill. The only thing that could have caused this is the wet food. The dry was the same bag for one month. They stay indoors and live in a controlled environment. He has had two nights at the vet and now I am doing IVs, etc. at home. He may not make it. This is so upsetting. My vet contacted Science Diet and they reported no problem with that food. Well, there is. I don't want other kitties to suffer.

Science Diet grain-free chicken and potatoes adult - My 2-year old Schnauzer-Poodle has stopped eating her food on and off for two weeks. Whenever she does eat, she eats grass and makes herself throw up. This has happened three times. She has now stopped drinking water. In addition, she is just laying around. This is it, no waiting, changing food tomorrow to Nutro or Wellness. Lost my mini-poodle back in 2004 when all the recalls were happening.

I started to feed my dogs the most expensive Healthy Mobility Science Diet line of dog food from PetSmart several months ago, after feeding them the large breed for years. One of my dogs developed rapidly growing lipomas resulting in 5 surgeries in two years to remove them. I wonder if this has something to do with the preservatives in the food. Then, after I switched to the Science Diet Healthy Mobility line several months ago, one of my dogs started vomiting his food on a daily basis. At first I thought it was because of the recent surgeries. But I decided to switch to Nutro Natural Choice, and the vomiting stopped. I wanted to share this with other people in case they had similar problems with their dogs. I do not work for a dog food company, retailer, groomer, boarder or veterinarian's office, nor does any member of my family or friendship group.

My dog Rusty has been eating this food since he was diagnosed with liver disease when he was one. It does help with his blood work (album), but has made him sick for years off and on! I've tried to switch foods to another LD diet but not many dog food companies offer it. Just today I found Royal Canine has it, but it's hard to get. It seems like Science Diet is in bed with most of the vets as all you see stocked to the max on their shelves is in fact Science Diet. It's a disgrace! When I spoke to the SD people on the phone, they told me there were no issues with their food whatsoever, but they had temperature problems with their unit in Kansas City.

After my beautiful 18-month old border collie began to have digestive issues recently, my vet recommended this food. Science Diet I/D is for dogs with digestive issues. My dog really liked it and I was mixing it with his regular food (Innova). Unfortunately, today I opened a can of the Science Diet I/D and I couldn't believe what I found: several large, very sharp, black pieces of what looked like rock or industrial grade ceramic. This substance was also granulated into the dog food. As I examined the food with a spoon, I could feel a sandy texture as I mashed it inside my dog's metal food bowl. No more Science Diet for my dog! I'll find something else.

I started feeding our one-year-old lab Science Diet Healthy Advantage puppy food in July and then switched to the adult dog food in early September. Our vet recommended it for her itchy skin. At first, our dog gobbled up the dog food but then started skipping feedings or sniffing the food and walking away in disgust. Not typical of a lab. She started eating less and less of the dog food. She was also getting progressively lethargic, sad and despondent. She lost weight and was looking small and week. I thought she was depressed or not getting out enough. Her energy level decreased significantly and she was acting like a 15-year-old dog. She refused to eat the Science Diet, but was clearly hungry, eating treats and people food.

I have used Science Diet Large Breed Light for over 20 years for four dogs. I will no longer be using it. Three to four weeks ago, one of my boxers became sick, vomiting, not taking water and declined quickly. I started her on chicken and rice but still no luck. So, I took her to the emergency vet. Her pancreatic enzymes were off the chart, over 6,000. They kept her no further vomiting and fluids. I brought her home. She did okay for 1-2 days (I think to please me) and then she declined so much she would not take anything so we had to put her down. When her brother (from same litter) started not eating, I thought he was slightly depressed so I did not think anything of it.

I brought an 8-week-old crossbreed pup who was extremely tiny, and the vets recommended feeding Hills Science (for small breed puppy) and gave me a free sample bag. I, having total faith in the vets, fed her this; and over the days, she got worse. She had the constant runs and was failing to gain weight/thrive. I wasn’t happy and switched her food to Raw, and the runs stopped, and she started gaining weight fast and is now a very healthy 6-month-old puppy. I honestly believe that if I had continued to feed her this rubbish, I would have had either a very large vet bill or a dead puppy. I would highly recommend to anyone looking into feeding this to avoid at all costs. It’s not worth risking your pet’s life over…

My dog has bladder stones and the vet prescribed Hill’s Prescription Diet (S/D) to dissolve them. My dog, who is not a picky eater, won't even go near this food. I can't blame him. It smells and looks disgusting, and its texture is like dried-up play dough. He threw up the one bit I did get him to eat. It is simply awful. I'm annoyed at the vet and won't buy Hill’s again. I've done some research that suggests that dogs in need of this diet prefer Royal Canin S/O, so we'll try that - but not before I call the vet and tell him what a miserable failure the Hill’s was. It cost me a lot of money; and worse than that, my dog is sad and hungry.

I just opened a new bag of Science Diet Adult Lamb Meal & Rice Small Bites, something they have eaten most of their lives. The first dog started to be sick about 4 days ago, then my male dog followed soon after and yesterday the baby. When the first one got sick, I thought she ate something from somewhere. I started eliminating everything. I just stopped all Science Diet food and hopefully they will get better. I checked last night for recalls and I stumbled on this page where another person had the same problem. Now I am 99% sure that the Science Diet Adult Lamb and Rice Small Bites is the cause.

My 3 year old healthy mutt runs loose on our 5 acres of woods very often and has eaten everything imaginable. She has never thrown up until I purchased and fed her an expensive bag of Hill's Science Diet Adult Lamb Meal & Rice Small Bites. She usually gobbles down her food. She picks at the Science, eats only a small portion and then throws up. Back to Pedigree!

I bought the biggest bag of dog food. At first, my dog would not eat it; then when he did, he got sick! Please refund my money or give me coupons in case I bought a bad bag!

Science Diet made my dogs sick. My 3 dogs refused to eat the big 35lb bag I just returned to the store. Two of the 3 have stomach issues from eating one meal from it. They have never refused Science Diet and are healthy dogs until that bag. I returned it for testing, Adult Small Crunchy Bites Age 1-6. Do not trust it!

After many years of eating Science Diet cat food without little or no problems, my cat starting having multiple distressing health issues including vomiting, diarrhea, lethargy and serious weight loss. Since he is 16 and I thought it could be aging and that I might be losing him. When I was out of Science Diet Senior cat food, I gave him some tuna and within a day he was playful and had energy I had not seen in a while. To make a long story shorter, we went back and forth between the tuna and Science Diet, including the prescription k/d formula that the vet gave me. Every time he went back on the Science Diet, the symptoms returned. The vet advised me that the tuna could be lacking minerals and other nutrients that he needed, so I went to the whole pets store and asked about grain-free canned foods. They recommended a brand called Hound and Gatos.

My yellow lab, only 7 1/2 years old, is right now lying on the floor with no desire to eat and has limited water intake. This is after two trips to emergency care for "pancreatitis". My vet originally recommended Science Diet C/D because of a high PH level and crystals in her blood. Within a week or two, she was deathly sick, but recovered fully while in emergency care. She relapsed again, as soon as she was on the Science Diet. We used a bland diet immediately after care and then introduced the Science Diet gradually. As soon as she was on the Science Diet alone, she would relapse. This is her third bout and I've stuck over $3,500.00 in her care!

I had been using Science Diet Ultra Allergen-Free dog food since I got my dog. I picked up a new bag and started feeding it to her. By the middle of the same day, she started vomiting and appeared to be in worsening distress. Thinking it was something else, I waited till the next day to see if she had improved. She had gotten worse by then. I took her to her vet. He had no idea what was wrong, and told me to bring her back if she did not improve in a day or two.

I purchased a bag of Hills Science Diet dog food, which is supposed to be a vet-recommended food for dogs, for my 12-year old Maltese. Our dog became extremely ill and we couldn't figure out what was wrong. He was very, very weak, no energy. He would sleep for 24 hours straight, hardly ate his food, barely drank his water and wouldn't get up. We took him to the vet, which cost us $300+ and they said he had Pancreatitis. They gave us pain medicine and we began feeding him Purina Moist Food to help him gain his strength. With a combination of his medicine and the new food, he began feeling great, running, playing, barking. We switched back to his dry Hills Science Diet food while continuing his medication and within 24 hours, he was back to the same illness! Very sick, very quickly. Then it donned on me, it was the Hills Science Diet food! What is going on here? My dog nearly died by eating this horrible food! I hope everyone reads the complaints and spreads the word about this terrible food that is clearly killing and making many animals sick!

My canine daughter, who had been on the same diet of Science Diet canned for mature dogs 7 and older, had always been on nothing but this food and never ate anything else. When she started not eating, we knew something was wrong. Then in the middle of the night, she had wanted down and off the bed. She had poop with blood! She was very ill. By morning, we realized she was getting worse by the hour so early in morning, after she also had more poop with blood and then vomited with blood, we immediately got her to her vet's office. She had, as far as we could tell, only been sick a day. Maybe less? At the vets, she had to be given IV shots for poop and pain, also blood work and antibiotics. The shot for the pain, poop and nausea allowed her to get some rest.

I have seen with my own eyes as have others, obviously that there has been and continues to be bad Science Diet out there. All were being recommended by veterinarians no less. It is making our animals sick and some unfortunately die! Most people these days do not have the high cost of vet care. How many animals and their parents have suffered because I never see a recall?

I have fed this dog food to our dog for almost 6 years now. It was prescribed by her vet and the only thing she could eat with her sensitive stomach. Like I have done many times before, I went to the vet on March 31st to purchase another expensive bag of this food. I took it home and once opened, she acted funny towards it. She didn't eat it at first, then after eating it for almost a week, became lethargic, had mucus in her stools and drank more water than usual. She normally eats twice a day, but with this most recent bag of food, she would only eat once a day, usually at the end of the day. My wife began researching after her behavior became very odd today. She began trying to eat dirt as well. The only thing that has changed in her life was this new bag of dog food. There is no doubt that this is the issue. I bought another brand and type of food on my way home from work tonight and she ate it immediately. She perked up and seems to feel a little better. This food is poison at best and should be taken off of the market immediately!

I bought a bag of Hill’s Science Diet dog food and noticed a "web" in the top of the bag as I opened it 2 weeks ago. I didn't think much of it because I didn’t notice any worms, but yesterday when I bought a bag, I found the webs again along with worms hanging from the webs! Gross! I brought the bag of food and the live worms to PetSmart. We opened two more bags of the same Science Diet food and they also had worms in it! The vet has recommended this food but we will never buy this food again! I am very upset!

I fed my dog Science Diet Mature Adult dry dog food. The next day, she began having diarrhea. We fed her the dog food for 1 week and her diarrhea got worse. We stopped giving her the food and switched back to her original food (Purina One) and her stools began to firm up. No more liquid feces. She has been back on Purina One for over 3 weeks now and still has very soft stools. Two very expensive visits to two different vets show her to now have elevated liver enzymes and low protein count. I truly believe that the Science Diet dog food made my pet ill. $1,500 later, she is still undergoing tests to determine what is going on and how to treat it.

Early Monday morning, I rushed my 3 indoor pets to the hospital, when they became very ill at the same time, the night before. The first immediate signs were drooling and smacking lips, and shunning food within hours of Sunday dinner. I visited them twice a day at the hospital, and watched bloody mouth and nose sores develop. They were immediately put on intravenous antibiotics, fluids, and pain medications. I was racking my brain trying to figure out what could have happened, since I use no chemicals in my house. I clean with a small wet washcloth and dry with a dry cloth, and use Ivory liquid soap or vinegar with water when needed. The only thing I feared was maybe bad food, and I had been feeding them with a doctor recommended science diet.

My Weimaraner, Wilson, was our first baby. We fed him expensive Science Diet brand of dog food for pretty much his whole life because that is what the vet recommended. In November of 2011, we bought a new bag and after about 1-2 weeks of eating that food, he became very ill, stopped eating and became very lethargic. I told my husband that I suspected the new bag of food, because that was the only thing that had changed. I bought a small bag of Beneful to try, but by this point, it was too late. He would not eat anything. We took him to the vet, did tests, started antibiotics, not really even knowing what was wrong. He passed away a few days later. After reading these posts, it makes me so upset to think that this could have been prevented. I am so angry that this expensive brand of dog food could have caused this! If we do get another dog, which we are hoping to do, I will never buy Science Diet again!

I had a cat that was diagnosed with kidney stones/urine crystals so I put him on Science Diet C/D to help avoid these issues. I put all my cats on it since I free feed. My 19-year old Siamese cat started showing signs of constipation, but I didn't know what could be causing it or that it was even a major problem until it was too late. By the time I figured it out, it was too late and he had to be put down. I was thinking it had something to do with his age until another cat started showing signs of constipation. Although my vet does not agree that the Science Diet cat food had anything to do with it, I find it extremely odd that both cats developed constipation problems. I am now trying to find a cat food that will help with the kidney stones/crystal problem and help with the constipation. I now have to give frequent doses of Miralax to my cat so he can poop.

I started feeding my two cats Y/D after my vet recommended it for their thyroid issues. After 3 weeks, my Russian Blue got very sick and had to be euthanized. A few days after that, my other cat also got sick, but was able to pull through. Both went into kidney failure and tests. Ultrasound shows that they had an acute toxin (such as antifreeze) in their stomachs.

Someone should investigate the nutritional adequacy of Science Diet canned and dry cat food. I strongly suspect that this food gave my cats cancer and hypertrophic cardiomyopathy. My cats suffered terribly and endured painful and expensive medical procedures. I had three cats at the same time: 2 of them had hypertrophic cardiomyopathy and 2 of them had cancer. What are the odds? All three died young for cats (one at age 5, two at age 9). On the other hand, my cats fed with Fancy Feast lived into their upper teens in good health and had shiny coats.

I made the mistake of not reading or investigating the ingredients in Science Diet (SD) and feeding it to my beloved Boston Terriers. When one of them came down with a severe, rare, and aggressive form of cancer of the connective tissue, I stated doing some investigating into Science Diet and spoke with several vets.

I have a poodle for almost 5 years. She is 10 years old. Before her, we had a poodle for 10 years. She was on Hills i/d for a bad stomach. My first dog and this dog are rescues. My poodle now was on science diet i/d up until a few weeks ago when the vet told us to switch to science diet k/d. Shortly after she started throwing up, having diarrhea and losing her appetite, as well as becoming very lethargic and her stomach was distended.

I have been feeding my female Maltese Science Diet canned chicken/turkey food for years. Recently she has had an upset stomach, is eating grass, has loose stools and sometimes even won't eat a "treat." Something is different about this canned food and I hope someone is investigating it and will give us an alternative soon.

I bought food for my dogs at the Veterinarian's office and have been feeding my two bichons and my cairn terrier Science Diet since they were born. They are now 6 years old. Up until now, I had not noticed any issues with the food; however, the dogs have been reacting strangely to the food the past month. I opened the container that I store their food in and bugs flew out of it. I was shocked, surprised and wondered how these bugs got in their food. Upon further inspection, I noticed that there were larvae throughout the container; therefore, I disposed of the food and thoroughly cleaned the containers.

After feeding our poodles this brand for over six years, I noticed a difference in their behavior--listlessness, constipation and not happy with their food. I looked closer at the ingredients and was surprised to find that where chicken used to be the first ingredient, it was now cornmeal and the second is now chicken by-products. Nowhere in the ingredient list was just chicken. Needless to say, I no longer use Science Diet and would recommend that all pet owners take a new look at the ingredients before buying.

I have fed my Maltese Science Diet Light for six and one half years. I thought it was the right food for him but he has recently become ill. At first loose stool, then vomiting. I took him to his regular vet and they put him on a liquid medicine. He felt better for a few days and then vomiting again. I took him back to my vet and he felt his abdomen and there was a lump felt. My vet took an ultrasound and told me there was a tumor that would have to be removed.They did the surgery the next day and told me he had cancer of the small intestines and it was also in the liver and lymph nodes. It broke my heart. I couldn't believe this was happening to my baby boy.

My English Bulldog and two Boxers have been on Hills for at least 8 months and they were doing okay. I ran into a bag that was "bad" and has given all three dogs lameness, wobbling, and no strength to stand. The suffering of diarrhea, vomiting, and stool with mucous took about 5 days for what I called the "inoculation" period. One of them had a fever of 103.5-104.2.

My dog was diagnosed and had to have surgery from bladder stones. Now the veterinarian says he has to be on Science diet for life. He would not eat that **. I was so upset. I did a lot of research and now he loves and eats Royal Canin Urinary SO. I am very happy with this prescription dog food. Also my veterinarian sent me some paperwork on what I can do to feed him other foods. The list says plain cooked chicken, plain cooked turkey, eggs, rice, peas, pasta, white potatoes, cabbage, cauliflower, bananas, and melon. I am so happy and my puppy is too! Hope this helps.

This is my 3rd large bag of Science Diet that has been infested with moths. I dumped the first bag in to a secure container that releases food when the lever is pulled. When I saw some of the food coming out had moths in it, I opened the top and they flew everywhere. I sprayed them and threw the food out. I cleaned the container and hung it back up. The same thing happened to the next bag I bought. I returned the contents with moths and webbing in the food. The pet store said it was strand and gave me another bag. I kept this one in the bag itself and opened it to scoop it into a smaller container about once a week. I just opened it (it is a 30 lbs. bag) and it is again full of these silvery little moths. My dog threw up the other night. He is a 16-18 lbs. King Charles Spaniel. I feel horrible. I am returning in tomorrow and I will never buy it again. Be careful with Science Diet food.

Our 10-year-old Labrador mix has eaten Science Diet for the past 7 years. For around the past five, she has eaten the adult light/low calorie in 40lb bag. About 6 months ago, shortly after we opened a new bag she started throwing up. Over the next several days she developed diarrhea and started to refuse to eat. I suspected we had gotten some bad food so I picked up a small bag of something else to see if that would help. She ate the food immediately and within a couple of days was back to normal. I thought maybe the light food was hard on her digestive system and I wasn't really sure if it was the food at all. So, when we ran out of the small bag of cheap grocery store food, I went back to Science Diet but I switched to the adult regular.

Please do not feed your animals Hill's Science Diet food. My 10-year-old Siamese has been the picture of health until now. He has been eating Hill's Science Diet c/d formula for approximately two years; it was recommended by our vet.

I have always used the Science Diet puppy food. All 3 of my dogs have become sick and vomiting. I stopped the food for a couple days and fed my dogs with chicken noodle soup, thinking it might have been a viral thing. I started their Science Diet food again. Vomiting came back again. So, they are eating chicken noodle soup and no vomiting at the time. I don't know if I need to purchase another bag of food, wondering if there is something wrong with the one bag they have been eating from. I have been buying this product for over 10 years and I don't know what to do.

The vet recommended Science Diet T/D on our first visit for our Maltese and Maltese mix, 3 and 2 years old respectively. After happily being on Blue Buffalo for 18 months, the vet convinced me, due to dental issues with the Maltese, to make the switch. I immediately noticed how dry my pups stool had become but figured this was due to the new food and its large size, although it was "small bites".

I have 10 rescues. When I feed them only Science Diet dog food, they all eat dirt. When I mix it with other food, they stop eating the dirt. Something is lacking in the food. As I read the reviews, I noticed many of the complaints matched things that happened to my dogs. I am changing their diets, even the one that has been eating it for 15 years. The one that eats W/D will find a new food as she vomits very often.

Our 4-year-old Labrador became listless and would not sit or lie down all day. This was due to her pancreas overreacting to fat. Our Labrador is on a fresh food diet with very little fat. Our neighbor brought over a leftover steak for our 2 dogs, and because of the higher fat content in the steak, Maggie's pancreas "over-reacted”.

My vet recommended Science Diet's z/d for my 6-year old Irish Setter. From September 2010 through April 2011, he ate the wet and dry varieties.

After a visit to the vet for our perfectly healthy Mal-Shi pup (eye-related visit), we acquired a free bag of Science Diet. So, of course, coming from the vet's office, I thought what could it hurt? Boy, was I wrong! I started integrating her regular food with the Science Diet just as recommended. She accepted the food fine and ate it for approximately five days without any side effects, or so I thought. By Day 6, our happy, vivacious, very energetic pup had now become gravely ill. She stopped eating, had diarrhea and was extremely lethargic. I was scared that she would not make it through the night and never get a chance to go to her vet appointment the following morning. I said a prayer and went online one last time hoping to get an answer.

My cat has eaten Science Diet Cat Food bladder health formula for almost two years now. He would throw up now and then, but he loved eating it and had no other problems. He is a little over two years old and has always had a good appetite, eating five-six times a day.

My girl friend moved her cat in with me and she started him on science diet! Well, his stools were stinky and he wasn't himself! Then, he was vomiting and we had to get him to a vet. Sadly, we had to put him to sleep! ONLY 7 years old, raised by her since he was 2 weeks old, we thought he ate something but reading this site, we are rethinking his demise! OMG, please pull this crap. This cat was her therapeutic cat and she is disabled, and since we found 2 new kitties. BUT Milo... we feel we killed him!

Science diet food is crap. I used it blindly since the mid 80’s when it was a good food for pets.

I have mixed breed chiweenie who we adopted at 6 weeks. He is now a year and a half. The pound provided us with a bag of Science Diet dry dog food so we kept him on this for some time. Then we noticed he started to throw up a lot and had bloody stools so my vet suggested we make a homemade mixture of boiled meat mainly chicken, carrots and rice to calm his stomach. We did that and in a few days he was fine. We also bought some organic foods and he loved them as well, but he really liked the Science Diet dry so we continued adding that to his food so there wasn't too much of a change.

My complaint has to do with Science Diet food for dogs. My daughter and I have two Schnauzer's who have eaten Science Diet all their lives. My issue is that we would buy the 20 lb bag and now the 17 1/2 lb bag is more expensive than the 20 lb. What is the deal. This is not right to get less food and pay more. There are 1,000 of people who buy science diet because they believe in the product. THIS IS NOT RIGHT!!!!!! What reasoning can you give me? Please send me coupons to make up the difference of having to pay more for less food. It does not seem like this should be able to be done. Thank you for your consideration.

Upon opening my 35 lb. bag of Science Diet Small Bites for Mature Dog +7, there are big bites an inch in size scattered among the small bites.

I have six Chihuahuas--mom, dad and their four kids. I bought Science Diet for a good food for my pets; what a mistake. I got the Science Diet that was from the vet’s. After only one feeding, three of my babies had seizures. I took the food away and thought that was that. Later in the month, after talking to the vet, I again tried to let them eat the SD. Never again. Four of them had seizures this time. This food is contaminated with something that is extremely toxic to small dogs. I recommend anyone with small dogs, or even large dogs, to beware of this product. I have switched to cooking for them myself and have had no problems.

I had two Labradors who both died within 2 months of each other. I started researching Science Diet which they had all of their lives. One was 11 and the other was 12. Both had tumors on their spleen. Our black Labrador had surgery last year and we were lucky that the tumor was benign. Our yellow Labrador got sick suddenly this April and she had a tumor on her spleen also. Unfortunately, she wasn't so lucky and had cancer in her lungs and liver. Their mother is still living at 16 and has been fed Purina all her life. I am so angry. I am so sorry that we ever started using what is supposed to be the best dog food there is.

I have been feeding my dogs Science Diet for years. They loved it. I have two English bulldogs and two pugs. But recently I have noticed a big change in the color of the food. The food is not as dark and does not seem to have as many oils. The smell of the food is also quite different.

I have had many cats which were raised on science diet, one which lived to be 25. I have had my younger cats on SD also but have noticed the fur on them turning white, one which is a Havana Brown. The fur started turning white about one week ago today. SD is on sale now at PetSmart but I'm not gong to buy it. I know the food is lacking something and with the price and risk it's not going to be worth the consequences.

Science Diet is not a top quality food as most of the bag is made of up ground corn.

I have had my dog on 50% Science Diet Mobility and 50% of the other dog food I’ve been using his whole life. He has been eating this for about 4-6 weeks. He is now been getting sicker and sicker for the past 2 weeks. He has been throwing up and each day he was not eating as much as he use to. He has been drinking water a lot. I decided 24 hours ago to stop giving him the Science Diet. He now has his appetite back, drinking normally and has not thrown up at all. I pray that I have stopped in time using Science Diet. I will never recommend this food to any of my dog friends. There is definitely a problem with this food if there are this many negative comments on the computer. I only wish that I had read this before I tried the product.

I have bought a case of 24 cans of the Science Diet cat food and have recently noticed my cat is not eating much or wanting to drink much. As well as now , it is also being lethargic for about the last three days. So tomorrow I will be contacting my local vet to have it checked out. What makes this most frustrating is that you make sure to only buy top quality food for your pet, then have that very food put your pet's health in danger.

I have used Science diet cat food for 20 years. I attribute my cat’s healthy long life to it. I have another cat who loves it also. She is only a year old. I am grateful for your product. I now buy it for our new puppy also. Thank you Science Diet.

The only difference in their life was the introduction of this new food. We never gave the food to our other dog, and she is fine. Both of the dogs ( a 12 yr mixed breed and a 12 yr bully) had some health problems but were doing well. Never in a million years would I have given this food to my dogs if I thought it would harm them in any way. I will never recommend this company or buy any of their food again.

We have five dogs of different breeds and have fed them a variety of food but have used Science Diet before and since all the scare of bad food I figured this one should be good. Been on it for a couple months now and ran out so I go buy another bag. Two strange things to start with none of my dogs want to eat all their food (stand indeed) but whatever. Then the day before yesterday, my daughter's large breed dog could not walk or stand and had diarrhea all over the place. Took her to the vet. The vet says probably a bacteria in her gut. Puts her on antibiotics. She's doing better. Then today, my son's Jack Russell starts doing the exact same thing! Called the vet and she says they are eating something making them sick. Well, unless my neighbors are poisoning them (highly unlikely), the only thing they eat is Science Diet ! No more and Science diet should be ashamed!

My 11 year old mini dachshund had a 1.6 lb tumor on his spleen, and he has been on Science Diet dog food. A neighbor said her dog had the same thing and fed the Science Diet. I don't think this was coincidence.

I purchased a 30 lb bag Healthy Mobility dry dog food for Adult 1+ large breed. My large breed dog could not chew the food as it was so hard. No problem I would just use my food grander and make it small enough for him to eat. Didn't work I could not get it to grand up as it is so hard. Why does all Science Diet dry dog food have to be so d**n hard? No, I do not like the smell of moist dog food. Sorry but after 5 years I'm going to try another dry dog. Thanks for taking the time to read this.

I have had my beagle puppy now for 3 months. I have not had one single problem with this food. My vet has recommended it to me and it is working out well for my dog. I'm writing to say that if your dog or cat isn't acting right, why are you keeping the dog or cat on the food for so long? It doesn't make sense! Don’t keep your pet on the food if you think it is making him or her so sick. This is pretty obvious!

I purchase SD Pet I/D dry food and canned wet food. I was giving my boxer the canned food and he started getting sick. I couldn't understand what was making him sick because he hadn't eaten anything other than SD Pet I/D food. He ended up going to the vet, getting hospitalized overnight, with IV hook up, x-rays and blood test, which cost me $500. He had gotten a bacteria. At this time, the vet told me it was something he ate. I explained I had not fed him anything other than the pet I/D food.

I purchase canned Science Diet Lite dog food every 3 weeks or so, by the case, each can is not completely filled with the product.

I have been feeding my 4 Chihuahuas Science Diet for 8 years. They are 10 and 11 years old and all 3 have diabetes and one has kidney problems from the dog food.

I've been feeding my 8-yr. old cat Science Diet for cats hairball control for a month now and she seemed to be fine up until 2 weeks ago. She started vomiting a few minutes after she ate. It never ever occurred to me it could be her food. I just thought, I have to take her to the vet. I let my bust life style get in the way and never took her to the vet. Then my husband and I went on vacation this past week only to come home and find she had went in a corner of our closet and urinated and died. Our friend who was looking after her said she didn't seem like herself and was just sleeping all the time and kept vomiting. We haven't had proper sleep yet. I feel so ill for neglecting and not taking her to the vet.

I have been purchasing Science Diet dog food for the last 12 years. I purchase the Adult Light Small Bites 40 lb bags. I have had repeated problems with this dog food having moths in the dog food. I have tried three different pet stores in the area and it is the same problem in each store. I sent an email to Science Diet and never heard from anyone. I decided to try the food one more time and still had the same problem. I contacted Science Diet at their 800# and they assured me they have a quality assurance department that checks for this and there is no problem with their food. I asked the customer service rep what happens when my dogs eat these bugs and she said her dogs and cats eat bugs all the time and it's not a problem.

We have two cats that about five years old. One cat appears has been vomiting lately and we believe it's due to her food. We feed them Science Diet Mature with Hairball Control. I just saw her eat five minutes ago and she threw it all up. I googled "cat vomiting science diet hairball" and found this site. After reading through some of the complaints and recognizing the same symptoms, I'm going to switch back to Purina or Iams.

I have an 11 week old kitten who were fed exclusively Science Diet Kitten canned food (of varying assortments) and started mixing in Science Diet's Nature's Best kitten kibble. Two days later, one of the kittens started exhibiting urgent urination and I noticed blood was present. After going to an incompetent vet and spending $1000 to diagnose the issue, I went to a second opinion. Urinalyses were performed and calcium oxalate crystals were present. A sonogram showed several stones in his bladder as well.

Because of a possible food allergy, six weeks ago, my active, fit and trim 65-pound Lab was prescribed Hill's z/d formula. She has a skin problem and is otherwise healthy. Since that prescription date, she has lost eight pounds and is lethargic. I believe there is no nutritional value to this food and that I have been starving her.

I took my new puppy to the vet for his first check-up. I had done some research on pet foods that were what I thought to be the healthiest for him and what are not. I currently have him on Blue Buffalo which I think is a healthy choice. When we were at the vet, she asked me what food I had him on and when I said "Blue Buffalo." She gave me a strange look and said she had never heard of it but would highly recommend Science Diet. But she said that her dog is on Purina and it’s good too without even bothering to ask if my dog was doing fine on his current diet. So why is she recommending this again? He's doing just fine! She gave me a bag to try for my puppy.

I have two 12-year-old Corgi's, they are brothers. I also had a Keeshond, who died a number of years ago. All three dogs have been fed one form or another of prescription Science Diet for their entire life, usually RD and TD for weight management and tartar control. The Keeshond died of a kidney tumor rupturing, I was too young to know why at the time until recently when my Corgis have become ill and I asked my mother about what had happened. One of the Corgi's just had his spleen removed because of a large tumor, which upon biopsy, has been identified with a type of cancer that usually attacks the liver and not the spleen. All three have had Cushing's disease.

I came home from work and my cat got sick with vomit and diarrhea all over the house. I took him to the emergency vet that evening and they told me he was extremely dehydrated and they asked me a lot of questions. I have been feeding my cat Science Diet wet food and dry food for two years. The vet kept him overnight, gave him an IV and monitored him. They did an x-ray when I got there and four hours later. Everything was fine. I checked the Science Diet can. It said it was good until 2011. I followed the vet's instructions and now a week later, he is sick again after I put him back on normal food. It is the Science Diet wet food because there is a mysterious white spot in the can which I assume was part of the food but it looks like mold. I will no longer feed him wet food.

My problem was with Science Diet wet cat food. It is the red can, culinary creations. This particular can, when opened, showed a large white area with a jellied substance along the edges. The can was not dented at all. This particular can was ocean whitefish, lot #P25. I contacted the company and sent pictures. They verified that the white area was definitely mold. I was lucky I spotted this and did not feed it to my kitties - I have three. I was hoping the company would recall this product but in return, they sent a $10.00 coupon and a letter thanking me for my input in their product.

About 4 months ago, I changed my cats over to Science Diet Mature Hairball control dry cat food per my vet. I've been mixing it in with their old food and gone completely to Science Diet as of a few weeks ago. About a week ago, I purchased a new bag and both cats were immediately sick. One has had diarrhea so badly the past few days that I am taking her to the vet in a few hours. I find it interesting that both cats were sick immediately after eating the new bag of food. I have gone back to their old food and one cat seems to be back on track, but we'll see today what is wrong with the other. After reading these other posts, I am certain that there is something wrong with Science Diet's food. Here's the info from the bag: K2130436 CH 202, Best before 02 2011, Product #7534 LCN 660.08.

Our cat began to vomit and foam at the mouth keeping us awake overnight. We took her to the vet and had to admit her to an emergency clinic to be monitored over the weekend. We brought her home and found her sister in the same state of distress. The only thing that changed was the new bag of Science Diet Adult sensitive stomach food we had started to give them. They were determined to have food poisoning and are recovering on fluid injections, antibiotics, appetite stimulants. After reading the same complaints online, I'm amazed of the similarity to the others. If I only had one cat, I would have continued to feed her the same food and probably killed her. This is scary as hell!

One of my cats is a bit "large" so we put him on Science Diet Lite. We were given samples by the vet. He started vomiting soon after his first meal and the vomit contained only SD Lite. We reverted to his old diet, alternating with SD Lite. The vomiting continued when on SD Lite. We discontinued the SD Lite and put him back on only Purina (but less of it) and the vomiting stopped. The cat seems fine now.

I bought a 20 lb. bag of Science Diet original dry cat food. One cat was vomiting and having diarrhea and is still not well. Another cat has diarrhea. The other cats are just laying around listless and have lack of appetite. The cats were picking at the food, and soon none of the cats would eat it at all. I returned the food to Pet Club and bought another of the same food with a different lot number. The cats won't eat that one either. I've been using this food for years too. I told Pet Club not to put the returned food in the donation cat bins. Something has definitely changed.

My cat was diagnosed with pancreatitis in March 2009. Although we tried all the sensitive stomach foods the vet prescribed, the only foods that didn't cause vomiting were Science Diet Original Dry Formula and Canned Meow Mix Tuna and Shrimp. Since Science Diet is supposed be better than Meow Mix, we've been feeding that for several months without any vomiting. In July 2009, we purchased another small bag of Science Diet and within 5 minutes of eating, my cat was vomiting. Thinking she had a pancreatitis attack, we withheld food for 24 hours, as recommended by our vet. Withholding food for so long is extremely stressful on our baby and watching her starve is agonizing. She began vomiting soon after eating more Science Diet.

I am involved in pet welfare and a longtime dog mom. We always have more than one dog in our house. My heart goes out to everyone experiencing problems with any pet product because we trust that companies polish their own products. I know what I went through after that one incident since I fed one of the foods from one of the recalls. I would like to thank this site for the accounts on Science Diet. Our recently adopted puppy who got sick (not related, but I will look into this now) was fed some Science Diet puppy while housed at the vets. I don't use the product, but to everyone who is concerned about their dogs' health, please check out the following publications:

My oldest cat was poisoned after eating Science Diet Savory Cuts in 2007 when pet food was tainted with melamine. Although she managed to survive that ordeal, her digestive system never returned completely to normal and she would have problems with vomiting and diarrhea and constipation. The vet put her on Hills ID Feline Prescription Diet for about a year; after which time, the vet recommended trying her on Science Diet. I was very skeptical about ever buying Science Diet again but the vet indicated that not only now was it safe, but it was a very good quality food.
