Rated 4.8 out of 5 by 48 reviewers.
Rated 1 out of 5 by This is not good dog food I am very disappointed in this dog food. My dogs had been eating another brand and the ingredients in Hills do not compare. My dogs would not eat the Hills except out of desperation and then had allergies to the ingredients. The reason I tried Hills was on recommendation from the vet. September 10, 2016
Rated 5 out of 5 by So convenient We live one hour from shopping. Chewy delivers food for both my dogs, wet and dry, and their flea medication to my door. The shipping is fast and all my orders have been correct. I will never shop in town again for pet supplies. September 9, 2016
Rated 5 out of 5 by When you need a lower fat dog food- My dog had pancretitis I needed a dog food with low fat. My little dachshund had a nasty bout with an illness called pancreatitis. This is a condition that in dogs may be related to not being able to tolerate higher levels of fat in the diet. The problem cause inflamation of the pancreas resulting in pain and vomiting and dehydration. Two weeks after the initial problem, the vet had us slowly restart her past diet. She again seemed to be having problems, having pain again. At that time the vet said to get her on a low fat diet permanently.. Looking at dog food websites, Hills made it easy to find a lower fat diet. They provided a dry weight percent fat which made it easy to compare the fat amounts in each variety. For that information, I am very thankful. The Adult Dog light food, is the one I chose. The fat percentage of dry weight is less than 10% as I recall. Initially, we supplemented the diet with cooked chicken and canned pumpkin and she gained some weight back. She has maintained her weight. (She was never overweight to begin with) She likes the dog food. She is a the happiest and sweetest dog on earth. I am very thankful that the diet has helped her. She is healthy again. April 9, 2016

Rated 5 out of 5 by Great price. My first purchase from chewy.com. Extremely pleased with the price, shipped promptly, and packaged properly. The dogs appear to be enjoying the food. December 2, 2015
Rated 5 out of 5 by vet recommended for weight loss My dogs have been on this dog food brand since they were puppies. Over the years my dogs have gained excessive weight. My vet recommended this food in order to take the extra weight off my dogs. It worked, I did not have to cut the amt of food I was giving them and the extra weight came off. The dogs look good and are a healthy weight now. And I don't feel like they had to starve to get this accomplished. October 2, 2013
Rated 5 out of 5 by Great Dog Food! My dogs love Hill's Science Diet Adult Light Dry Dog Food! It has controlled their weight and they are very active and happy! This is a great product! November 25, 2015
Rated 5 out of 5 by GREAT DOG CHOW I've been feeding my pets this dog food for many years. It's great for weight control, helps maintain a healthy pet, and my dogs love the taste. Once they have reached their weight goal I add a small amount of high protein to their diet such as baked chicken or fish and I have had great success. July 26, 2015
Rated 5 out of 5 by The Best Dogfood I've been feeding Science Diet to my past and current dogs for over 24 years. I like the fact that when my vet asks which dog food that "my guys" are currently on, and I answer Science Diet, there is never any question that they're receiving proper nutrition and healthy food. Ordering through Chewy.com has made my life much easier. The food arrives when promised to my door step. July 7, 2014
Rated 5 out of 5 by Vet Recommended Our Vet said she feeds this to her dogs and recommended it for our labrardor Lucy. I was impressed by the high amount of fiber in this product, which will help to satisfy Lucy's appetite and help her maintain good digestional functionality. On top of these attributes it provides Lucy's nutritional needs, more so that cheaper foods. February 14, 2012
Rated 5 out of 5 by Great dog food This is a great dog food for my pit bull! He has sensitive skin and a very sensitive stomach and science diet is great for him! The only dog food he can eat. I would recommend science diet, especially for dogs that have sensitive skin and stomach July 5, 2015
Rated 5 out of 5 by My Dog loves this food! My German Shepherd loves this food. I've used Science Diet for about a year now and she looks great, feels great, has a healthy coat, and is back at her normal weight again after gaining 5-10 lbs on her previous food. I am also pleased to see it has improved her digestive health- I'll never use anything else. November 9, 2014
Rated 5 out of 5 by The best LIGHT Food My 4 Sheepdogs love it and the two that really needed to lose the weight have....they get it twice a day with fresh Chicken Breast and their coats look wonderful I believe in Breakfast & Dinner for my dogs...I don't think once a day is good....so the Light is perfect for them... March 20, 2015
Rated 5 out of 5 by Recommended to us at Vet's office This has been our "go to" dog food for our Lab-husky neutered member of the family. He loves it, and it has kept him happy and at a good weight for the past 4 years. It is easy to store (in air tight container) and we found it at the best price at Chewy.com August 4, 2014
Rated 5 out of 5 by Hills Science Diet This product is a real value through Chewy.Com. I find that it keeps the weight down on my small miniature schnauzers and they gobble it up twice a day. Happy and Healthy Pups means a happy home and owner. April 28, 2014
Rated 5 out of 5 by Dog approved Just recently bought this for my 2 labs that could stand to lose a few pounds. They both love the taste of it, I had no problems switching from what they were eating before & you can't beat the prices that Chewy offers! November 26, 2014
Rated 4 out of 5 by To much dust (yellow food dust ) in product. Recently I have purchased three bags of the adult light and the product has an unusual amount of food dust . The dust does not appear to harm the product, just a waste of food and non usable product. February 14, 2012
Rated 5 out of 5 by Great product! The is the only dog food my dog can eat. It was recommended by my vet and has been a lifesaver. She has pancrecretis and this food has been great for her. October 24, 2014
