Rated 5 out of 5 by I have been using this brand for years! I have been feeding this exact food to my dogs for years. Ever since I had a diabetic Dog that needed to drop some weight.

Rated 5 out of 5 by Healthy Dog Food I have a small dog who loves the smaller bites of food. Hills Science Diet Food is good quality dog food at reasonable prices. I alternate this dry food with the canned soft food of the same brand. It maintains my dogs weight at a healthy level. July 14, 2016

Rated 5 out of 5 by bag this was my first time at chewy. good fast shipping, but the bag had tape on it. that kinda bugged me, but felt, looked and smell fresh, I wouldn't buy a bag like that at a store, so I don't expect that. June 21, 2016

Rated 5 out of 5 by My dogs eat it! Got 2 picky eaters but they both can agree on this dry food! June 5, 2016
Rated 5 out of 5 by Our dogs love this food. We have a 7 year old dog and a 2 year old dog, so I mix the small bite food with the larger kibble and our dogs go after it! The combo suits both dog palates and we never have trouble getting them to eat any more. May 19, 2016

Rated 5 out of 5 by Healthy Food for Obese Dog This is a great food for my little fat beagle I have that is a very easy keeper. I have been able to drop some weight off her and keep her healthy at the same time. Her coat is pretty with a shine and she as lots of energy. May 11, 2016
Rated 5 out of 5 by Great product and great customer service Good experience with my order. Thank you for the service. May 14, 2016
Rated 5 out of 5 by Great option My dogs are really enjoying this food, I had purchase before the one with bigger pellets, but this tiny ones work better, they eat much slower and this definitely helps them not being hungry again so fast!! March 14, 2016
Rated 5 out of 5 by My picky eaters love this products. Its the perfect bite size, especially for my min pin with him having some of his teeth extracted. Both of my babies love the taste. March 9, 2016
Rated 5 out of 5 by My dog acts like he's starving when I serve this! My dog acts like he's starving when I serve this! This is the best price for this size bag, at least that I can find, particularly when you count "free delivery." I like not having to carry that large and heavy bag to the car and inside my house! February 17, 2016
Rated 5 out of 5 by Highly Recommend for the Diabetic Dog! If you have a diabetic dog like us then this is the right dry for you that is "not vet buy from only"! This has more fiber in it then "those brands" and it is easier to eat for all types of dogs. It does last longer too as far as how often you have to buy it. At least for me it does. You have to find your balance of how much to give your dog due to weight and size plus if you add anything else to it. But, once you get the just of it things move right a long at eating time. One thing since this is a high fiber kibble you may want to up the going out to potty factor as well until his system gets use to it and you get use to that part as well. They will need more outdoor time. February 11, 2015
Rated 5 out of 5 by This product is made by the best company for animals! Chewy is the best site to order your pet products. I have ordered many items from them and they deliver on time and the product is always what you excepted to have delivered! There is not better site for ordering what you need for your animals!

Rated 5 out of 5 by Fuzzy Fuzzy is her name. She came to live with me and my husband after my mother passed away last year. Fuzzy came from a shelter and I didn't want her to go back there so we took her and gave her a forever home. She was pretty fat and she needed to lose weight fast. I have tried alot of different dog foods and this one Hill's Science Diet Adult Light Small Bites really works for her. She loves the food and she is losing weight. She is a very good dog. My mom gave her treats all day long and of cause she gained alot of weight. She is on the road to a slimmer and more fix dog. Thanks for Science Diet. And I love the shipping right to my home. Thanks again Bonny March 5, 2014
Rated 5 out of 5 by Vet recommended My dog is diabetic and the lite seems to be doing a great job on keeping her levels good... February 5, 2016
Rated 3 out of 5 by I didn't realize that it had pork fat in it. Good service and fast delivery so I'm happy with that. I looked at the ingredients and saw only chicken products. I stopped reading when I got to the vitamin list. After I received the order, I realized it has pork fat in it which we definitely do not want in our house. So anyone else with that concern should be aware. November 18, 2015
Rated 5 out of 5 by GREAT DOG FOOD I feed both of my adult HUSKYS this food (regular adult chunks) for weight loss and to help them maintain a healthy weight. I add a small amount of lean, baked meat for extra protein. I also have a small poodle with a heart condition that I feed the small bites to maintain good health for her. All of my pets were rescued and this food helps keep them all healthy since I have no idea of the care they received in the past. Great food that is recommended by me and my vet. September 15, 2015
Rated 5 out of 5 by This is a great product!! I love the small bites for my toy poodle & my sheltie. When I opened the bag of this dog food I was astonished at how good it smells. My babies absolutely love this product. Thank you for making such a great food with dogs in mind!! Jeannie November 27, 2015
Rated 5 out of 5 by Dogs love it My two Caviliers love this dog food and it helps control their weight. December 26, 2015
Rated 4 out of 5 by It Actually Delivers! I started my little girl on this formula for the first time a couple months ago. She had put on some weight (training classes = lots of treats!) and has luxating patellas. The transition was smooth, her coat looks fabulous, and best of all; she #2's consistently and its always a healthy consistency (sorry but this is a big deal for her!). The only con is that I have to mix a tsp of wet food to get her to eat it. I've never used a Hills product for my pets before, but I must say that with their research, quality control and performance, I am impressed! January 7, 2015
Rated 5 out of 5 by A New Food to Try We have two miniature schnauzers and have just started using this food choice for our dogs because our vet uses it for their dogs that are kenneled. Right now I'm mixing it with the remaining food we have so their tummy's don't get upset with the food change. Our dogs seem to really like it because the bites are nice and small. I imagine the taste is pretty good, too! September 4, 2015
