      I have a 4 year toy poodle that just would not eat dog food. It would either make her sick or she just would not eat it, I was very worried about her and just on a whim I purchased a bag of Hill's Science Small Paws and she loves it! This has been a godsend to my family. We love our fur baby, she is a extremely important part of our family and to see her eat something that is healthy and she loves. She is more alert and active since eating Hill's Science. This is a great dog food!

      Best diets on the Market. A must read. Ok everyone I am sure you're thinking no way. Well yes. I have a 12 yr old male Siamese, Balinese cat who is 12 going on 2. I used to have him on other diets, I got him from my vet at 5 yrs old and he was on whatever the cats opened. They had him on Science Diet and he was a gorgeous cat, beautiful fur and healthy. When I got him I decided after all the hype about grain free diets to try them. One is no longer on the market, thanks Smucker's. Because of you I now have my cat on foods that are good for him. :)

      The other dry food was Blue and within two years of putting him on Blue, my cat developed neck lesions on 4 teeth and had to have them pulled. The vet said he thought it might be stomatitis but it wasn't! It was all the multiple pre and probiotics they were adding into the food. If you ate that many pre and probiotics your gut would be killing you. They only need lactobacillus if they are out of balance and you can use your own Culterelle and put in canned food or sprinkle on dry food. I use one for me and half for him. Since I began using Science Diet he is no longer vomiting, has normal stools, no teeth have been pulled, no neck lesions. IT WAS NOT STOMATITIS! When too many pre probiotics are added, it disturbs the natural flora and causing bacteria to go up the esophagus into the mouth and develop neck lesions.

      I took him off the NO GRAIN DIETS, put him on Science Diet optimal care and also as he got older he is 12 now I have him on indoor 12 + and also on Youthful Vitality. My kitty is healthy, and happy and never in better health. I will NEVER put my cat on a no grain diet. What do they eat in the wild, birds, mice etc and what do birds and mice eat? GRAINS!! When someone tells you corn gluten meal, it is that tiny piece of white in a kernel of corn, IT IS PLANT PROTEIN. Do not let people tell you that grain free is better. NEWS FLASH FROM TV 6 it is not better for your animals. They just had a detailed news story on no grain not being good for your pets. I will stay with SD as long as I can. I just hope they remove the wheat again...but my cat loves it and won't eat canned nor human food. So he gets a variety with SD. Don't let the commercials or pet stores tell you different. No Grain diets are not better for cats or dogs.

      I have had cats for 30 years. Early on I thought it was crazy to purchase one of the high priced foods. But when we were stationed in the Philippines we adopted a Filipino kitten (we already had a 3 year old cat). The kitten was scrawny and bony, and had coarse, wiry hair. I found out those were typical features of those cats. One day as I was leaving the veterinarian on base I saw the vets interacting with some stray cats outside. They were beautiful, soft and healthy looking. I assumed they were not Filipino cats but the vets told me yes they were Filipino cats. I asked why they looked so healthy and they told me it was because they fed them Science Diet. I immediately switched my cats to SD and sure enough, the Filipino cat quickly became beautiful, healthy, and softer than ever. Our other cat improved on it as well.

      I don’t know how long the Filipino cat lived because my ex-husband got custody of her, but my other cat lived to be 18. Meanwhile I adopted a stray cat that was estimated to be 5-10 years old. She already had Feline Leukemia. I had her for 15 years, meaning she lived to be roughly 20-25 years old, even with the Feline leukemia. She was never sick in all those years, until the day before she died but I knew it was her time to go. My vet was always amazed by her. I fed her SD the entire time I had her.

      I have moved numerous times over the years, and therefore had to switch vets as many times. I have asked each vet about the SD, as I had always heard some unfavorable things about it. Every single vet has told me that SD is a great food, and that ALL of the foods have fillers but SD is the only one that discloses it on their label. Three years ago I adopted a dog (approximately 8 years old). I had her fully checked out by my vet and she had no health issues whatsoever. I decided to listen to all the pop culture stuff about the pet foods, so I put her on Blue Buffalo grain free.

      Within 6 months of feeding her the Blue Buffalo she rapidly became 10 lbs overweight! I was feeding her less than the daily recommended amount. I switched her 4 or 5 times over the next year or so to various weight management foods. She didn’t like most of them, and didn’t lose any weight at all. I finally relented and switched her to SD Perfect Weight and she has lost 6 pounds over 6 months. She loves the food, and remarkably, about 2 weeks after switching, her energy level had noticeably increased and she seemed happier. She is now about 11 years old.

      Oh, and one more thing. The manager at our local Petsmart told me several months ago that Science Diet had been bought by Mars candy bar company. That FALSE info delayed my switch back to SD. Fortunately I mentioned that to my vet who told me that was false and supported my switch. Bottom line....I think I’m going to stick with Science Diet.

      Hill's wet and dry lamb and rice and senior foods - I have been feeding Hill's to my dogs and cats since I was a kid. Presently, it’s the only food that doesn’t make my dog sick with diarrhea and vomiting. She also has terrible food allergies that present themselves as hives and hot spots. I fed Hill's lamb and rice until she needed the senior food and I still do not have any issues. I did get a few cans of the recall food. I know she must have eaten at least a couple. Thankfully she made it through. She’s ok and still on Hill's and doing well at 12. Most people that meet her assume she is far younger than she is. That says a lot for the brand.

      I have fed Science Diet for 16 years with no problems what-so-ever. They never had gas issues and their poo didn't stink. I lost my 17yr old Yorkie, Izzy, this year. I got her as a rescue, literally on death's door. She lived a wonderful, healthy, happy and loved life. I also lost my 11yr old Boxer, Wesley, this year. WHAT A HAPPY LIFE that MAN lived!! I miss him beyond words. I still have my 16yr old, Jolie, although blind and losing teeth... Otherwise healthy. She has never cared for wet food so the tiny bites are perfect for her tiny mouth and lack of teeth.

      I have been using Science Diet since we adopted our Lab-GSH mix four years ago. It was supposed to be high in animal protein and low on grains. Well, something changed. A month ago, while I was away, our pup had a seizure. Then a couple of weeks later, another. The vet says, genetic disposition, don't worry. But we noticed she is much more picky about eating, and sometimes chooses not to eat. She was also an eager eater. Noticed the composition of the bits were clearly different. Now, she won't even finish a bowl of food, wet or dry. I'm pretty sure something has changed, if I can't see it, our dog definitely knows, and is not happy about it. Looking for something better.

      When we made the switch a couple of weeks ago to Hills Science Diet I thought I was buying the best for our puppy. A couple of days after he started eating the food he threw up. I know that is not uncommon when switching foods so we continued to feed it to him. Recently I noticed he was eating more grass and today he wouldn't eat a thing. He was lethargic and overall not well. I spoke to an animal professional who told me some dogs have a negative reaction to Hills Science Diet dog food and to take it away from him. I have now removed it out of my house and started feeding my puppy pumpkin puree to help settle his stomach. For as sick as my puppy was acting - there is no way I will ever purchase Science Diet again.

      I rescued a black Lab back in March. He was having issues with digestion and my vet wrote a prescription for the Hills Science Diet i/d Digestive Care Dog Food. I purchased a 8.5 pound bag of the dry dog food at my vet's clinic. He ate the food for two weeks and had significant approval in his bowel movements and he appeared to be feeling better and having more energy.

      Recently I ordered a large bag from and fed him from this bag. After two meals my dog began to shake and tremble uncontrollably and appeared to be terrified. This went on for 5 days over a holiday weekend. He would not leave his cage nor go outside to relieve himself. I took him to the vet and she prescribed anxiety medication. Nothing changed. I kept suspecting something was wrong with the i/d bag of food I received from I went to the vet and purchased a 8.5 bag and after just two feeding he was back to normal.

      After consulting with my vet I contacted Hills Customer Service. They advised me they would have refund my purchase and that they would send me coupons in the mail. To this date I only received an email survey from Hills on how my complaint was handled and I received two five dollar coupons. That's it! No apology letter, no follow up, no concern of how that food made my dog so ill. I am considering have the food analyzed by a lab. Please be aware. I would not want another dog and family to suffer like we did. This all occurred in June 2019.

      After using Hill's Science Diet for 20 years for both my cats & dogs, I am appalled to learn that they outsourced production of portions of their product to China. Many pets died as a result of their greed. What concerns me also is that this product was recommended to me by my veterinarian. I gladly paid a premium for a product that I thought would be the best for my pets health.

      The fact that commercial dog manufacturers have overlooked is that pet owners do not think of their pets as disposable. We value them as much as our own family/children. Because of Hill's negligence in maintaining strict quality standards in directly overseeing the production of their products, I AM BOWING OUT OF ALL COMMERCIAL DOG FOODS FOREVER. I have educated myself and will continue to do so in order to prepare a nutritionally balanced diet in my own home! YOU HAVE ALL BETRAYED MY TRUST!

      My family has had our cats on Science Diet from the start cause my 2 family members work at a vet clinic and get Science Diet at a low cost and my cat was the first to go and he died, no sorry. He suffocated because of a mysterious liquid filled his lungs and killed him and the vet had no clue why he had fluid in his lungs and then the next cat died with a mysterious illness and the next and the next and I never put two and two together that it was the food until I heard a podcast about how bad the food was and it now makes sense that that food will NEVER be given to my now dog and cat.
