    I feel like Hill's Science does not care about our animal. They only care about lining their pockets with your money. Their shipments is horrible. I had wait a week for my cat's food. While I was expecting it 3 days after I had ordered it as said in their site and email. Now I had to go purchase more food that she can't have according to the vet, like I have the funds to just oh willy nilly and just buy more food. This place feel like a scam. Like why should pet owner have to special order food for your pets, why isn't this food in store where it accessible pet owners who need it. Like I said this makes you feel entrapped as if you have to buy from them. Day 1 of boycotting Hill Science

    At first I was buying a food called Blue Buffalo. My dog I noticed was throwing up and he scratching his ears and biting his paws from bad allergies. I purchased some Science dog food and I noticed it his coats looking nice and shiny and he's not shedding too much and he's stop scratching his ear and biting his paws. From now on every month I'm going to buy it for him. It cost $10 more but my dog's worth it. Good stuff

      HI am a breeder of Golden Retrievers for over 20 years (Mochavulin Golden Retrievers) and I have always been loyal to the Brand because of the supposed excellent formula and specifically formulated for Large Breed dogs. I have used Hills for all my adult dogs (ranging from the normal food, as well as the Prescription diets). Over the years I have had issues with litters of puppies that did not have normal stools and reported this to the Hills Representative in South Africa (Marycke **) as well as our local rep. After this, a new formula for the Hills Large Breed puppy was developed (Perfect Digest) which I did use, and did not experience any issues.

      However, in 2025, I was not able to get the new Perfect Digest and opted for the Hills Large Breed Puppy food. From the onset of weaning the puppies onto solids, I had issues with their stools and gastrointestinal upsets. Puppies were evaluated by a vet and checked for any underlying issues (giardia, coccidia and so forth) with negative results all round. I recommended that all my puppy owners continue on Hills LB Puppy, but the issues remained for over 12 weeks. After 90% of the puppy owners continued to struggle with their pups intestinal issues (resulting in extensive vet bills and regular vet visits), I recommended that they change the food to Royal Canin Maxi Puppy or Royal Canin Golden Retriever. The results were immediate and all intestinal issues was resolved within less than 24 hours.

      I have reported this to the Hills Representatives in South Africa and also asked the puppy owners to send emails of their experience as these issues were not related to a specific "batch" of food as the owners are located all over South Africa, from Gauteng, to the North West, Bloemfontein, Cape Town and Plettenberg Bay. This is very concerning and distressing for the owners and I have requested Hills to investigate this further as this has affected over 22 puppies in total, including 2 of my own puppies. I would appreciate if Hills can act on this urgently, have individual discussions with each of the owners and offer a refund for the food that they purchased, as well as reimbursement for the veterinary costs that they incurred - which was completely unnecessary and unacceptable.

      I was shocked that your cost for a 15.5 pound bag at petco went up to 64.00 from 51.00. I simply can't afford it with two big dogs anymore. I bought a cookbook for dog crockpot recipes and will make my own from now on.

      Hills decided to change formula on prescription dog food. However they did not feel the need to let the consumers know. The new “formula” caused gastro issues with my dog and she’s NEVER had problems with it before. Stomach gurgling, gas and constipation is what we got out of the new formula. Hills is off my list for good! They no longer care as the person I spoke with tried to gaslight me and blame my Vet!! I’ve reached out to the higher ups and yep you guessed it.., nothing! They only care about the money.

      I have been using Science Diet hydrolyzed foods for my dog since he was a puppy and found out that he could not process proteins. In the last year their quality has been getting worse and worse. You never know what you are going to get till you open the can. I have no issues with the dry. The turkey either comes hard as a rock, or liquidy. And in the last two weeks my dog was getting sick with the new batch, but I did not know it was the turkey, till we spoke to our vet who saw nothing wrong in his gut, and by product of elimination. We stopped feeding him the turkey. Gave him the chicken and rice instead. And he finally stopped getting sick. I am going to be switching my brand, I cannot take the chance of poison in my dog's food.

      This brand is garbage. Made my shihtzu sick. There was no gluten-free options as she was allergic, and it is overpriced. Makes our new rescue have super loose stools for one who only gets kibble. I wouldn't eat this if the world ended and it was that or death, I'd have such bad upset if I did, I'd be dead anyways.

      Food made cat sick multiple times. Went through the whole process to get a full refund since website says 100% guarantee and vet said they were "good about refunds." Over a month later they send me 2 $15-off coupons I can't use at the same time to "refund" me for nearly $80 in cat good. The guarantee on the website is fraud.

      My cat did enjoy eating the adult chicken dry food. I purchased a new bag with new imagery and discovered the food was shaped differently. I offered it to my cat and she refuses to taste it. She won’t eat it buried or mix with the old. Something about the aroma turns her off. I had to purchase another brand of cat food. She may not be a fan of the new brand but she’s eating it. She refuses the Hill's Science Diet Adult Chicken new formula. I sent my concerns via email. They promptly responded to my concerns. However the formula change has caused me to purchase other brands.

      I’m so upset with the recent quality of their dry food, particularly the adult chicken one. On two separate occasions now it has given BOTH my dogs the extreme runs, with gurgling stomach and flatulence. As we speak, I am currently making them boiled chicken and white rice and giving Proviable to tame their insane digestion issues. My oldest has been on Science Diet for 6 years, but after this terrible quality control or recipe change, I fear I am done and will search for a new dog food. What a shame.

      Something in the quality across two variations of their dry food has changed. Beliving we had bad batches we toss 90lbs of food for new. This was a back in May of 25. This week we received a new bag and one of the two dogs stopped eating altogether. The second dog that has a history of eating on schedule and voraciously began to eat slower and not finishing their food. This morning I found both dogs eating grass and stepped away after one sniff. Cleaning the bowls did nothing. Both refused to eat. Upset at this I purchased a competitor's product in small supply at Tractor Supply and both dogs eat like they hadn't been feed in day. I can confirm this to be true. Something has changed at Science Diet and it is not good.

      My Sophie is a year old. Very active, 67 pound, somewhat overweight, Staffordshire terrier who is the most finicky of finicky eaters. I started out cooking her food, then changed to Freshpet, then to Purina Pro Plan and I've noticed lately that her energy seems low, doesn't seem to get the zoomies as much and wasn't nearly as playful as I know her to be. So, I asked Grok the other day what is the number one, best adult dog food, for weight loss and energy restore on the market and without a hesitation Science Hill Diet came up, so I immediately ordered.

      LITERALLY, 2 bowls later and the very next day Sophie was spring through the backyard, she was zooming all over my apt and was acting like. 7 month old puppy! I was so excited to see this shift in her! Her stools look great and let me say this, Sophie has never finished a whole bowl of dog AND LICKED the bowl clean, well she does now! She loves loves loves the taste of Science Hill Diet! I recommend 10/10 and I am now a forever loyal customer!

      I have been a Hills customer since 1993 for both wet and dry dog food. My last two orders are hit and miss on quality and consistency. Look at the dryness of the white dish compared to the orange dish. I opened both of these out of the same case this morning. My previous order was all dry as well so I just added a bit of water, but my dogs still didn't care for it. Not a happy customer. Going to try out some other wet foods comparable to this.

      Received your reply to my review…Here’s the confusion…you inform me that the dry matter on the Hills Science KD dry for cats is .54 phosphorus dry matter. Then you said I should read the bag nutrition and see the .55 phosphorus dry matter. My bag of Hills Science KD dry cat food reads .75. So that’s where the problem lies…

      I've been using Science Diet Small Bites for 9 years. We started with puppy, and now on Adult. I have a Yorkipoo, 10lbs. She has never had a problem with digestion. On a fun note, she loves taking one out and playing with it, then eating it. She even takes her empty bowl and brings it to me to fill. I'm getting a puppy, so I'll be starting all over again with Science Diet Puppy Bites.

      Our Shih-Tzu suffered from pancreatitis December 28th and we are uncertain if he also had IBS as well. He was on antibiotics for a week the first time, but it came back. His doctor is great and has regimented Science Diet I/D. Before the pancreatitis, he only ate Science Diet dry kibble, but now we have to mix the I/D low fat with dry kibble. I'm very much against "wet" food because of their teeth (dogs and cats). He was eating rice and chicken breast with zero skin or fat while we were fixing his belly. It was probably a 6 week period and we caught it immediately. My only concern is he's lost 4lbs in about 2 months (though he weighs 17 lbs, so he's not underweight). It's just he's always been around 20lbs. He turned 5 in January.

      But back to the review. Science Diet has always been great for our animals. My ex worked for Science Diet and they do truly care (or did) for animals. He hasn't worked for them in a while and he's an ex for a reason 😉. I recommend Science Diet, but they definitely charge a ton of mark up on their food. We would eat grilled cheese sandwiches forever to make sure our fur babies were taken care of, however.

      We have always fed our dogs this brand. But all the sudden it is has started making both our dogs sick. Don’t know what has changed but we will be changing brands. Which is unfortunate because they really like their food and this brand is slightly less expensive than the other brand our vet recommends.

      Had my dog on Benefil Incredi bites & Incredi bites pate. Thinking Hill's Adult 7+ would be a healthier choice, apparently, my dog doesn't think so and ate a few bites & gave up. The consistency of it sticks together like clumpy glue. I feel bad because I have to go to work and he hasn't eaten & will have to wait until I go back to the store after work. I feel I made a bad choice buying Hill's.
