Rated 4.8 out of 5 by 139 reviewers.
Rated 5 out of 5 by Hill's Science Diet is a real GOOD dry dog food! I have many dogs of various sizes and breeds. All of my dogs like eating the "small bites" sized kibbles and will usually clean their bowls without me having to "doctor" it up with canned food. When my dogs eat Science Diet, their stools are normally firm - real nice "side effect" when you have doggies with shaggy "pants"!.I have fed them lesser-quality food and experienced disastrous results - I spent a lot of time washing dog pants, as many of my canine friends occupy the same spaces as I do and there's NO room for any doggies with "poo-pants". All of my dogs have shiny coats and appear to be strong & healthy. I would recommend any Science Diet variety to anyone who loves their pets! You can trust Science Diet and the Hill's company to manufacture a high quality and healthy product for your pets. May 16, 2012
Rated 5 out of 5 by Happy dogs start with good food! I have 2 dogs, a Jack-russell mix and a lab mix, both eat Science Diet Adult small bites. The lab mix is extremely picky and would rarely eat all of her food at meal time, but since we changed to this food there is never a piece of food left. She looks forward to meal time now which makes life a lot easier! The jack-russell mix has issues with her skin and this food really seems to help with her skin. Both dogs love the small bites and the taste of the food. We have definitely found a food to stick with! May 16, 2012
Rated 5 out of 5 by improved dog's coat and health When we adopted our dog he was thin, not very active and had a thin coat with bald patches. We were given a small bag with store brand food for him to eat. We knew we wanted to change him over to the Advanced Fitness Small Bites so we mixed it in with the food he had been receiving. The dog wouldn't eat his old food; he would spit it out and only eat the Advanced Fitness Small Bites. After only a month there was a marked improvement in not only his activity but his coat as well. We now have an active dog with a thick, healthy coat without any bald patches. September 8, 2013
Rated 4 out of 5 by This dry food is the choice of my seven small dogs I have six Shih Tzu and one Toy Poodle and have tried several different well-known "quality" brands, including three varieties of Science Diet. This seems to be the choice they prefer by far. Since switching to Science Diet Adult Small bites, I do not have any problem with getting them to eat it. The pieces of just the right size for their tiny teeth. Their skin and hair have been healthier since we settled on this choice and their overall health is great. May 16, 2012
Rated 5 out of 5 by Great Product When My pup was small she had intestinal problems and we switched her dog food to science diet and she and her buddy have been eating it ever since with no problems and I would not change it for anything. They love this food both my dogs are large dogs and a large bag lasts me a month so its a great value :) Highly recommend. May 17, 2012
Rated 5 out of 5 by Best dog food EVER! My 3yr old Norfolk Terrier ONLY eats this product. It was highly recommended by the vet & not only does my dog love the taste, but it's the top of the line in nutrition & all excellent ingredients! I highly recommend this product for all dogs!!!

Rated 5 out of 5 by Great product I won a bag of Science Diet small bites 15 years ago with my Jack Russell Terrier, Rascal, at an obedience trial. Rascal was a picky eater, but he ate the small bites with no problem. Rascal lived to be 15 years old with no health problems throughout his life.We currently have 3 dogs, Labrador 10 yrs, Jack Russell 9yrs, and Norwich Terrier 17 months, who all eat Science Diet small bites. They are all healthy, inside and out. My husband and I swear by Science diet. If someone offered us another dog food free for a year, we would decline. Way to go Hill's. Great product! May 19, 2012
Rated 5 out of 5 by This product has many great features; My 3 Labs love this food and has thrived very well since being on it. I was hesitant after all I have gone through with the other foods I have tried before hand. My Vet highly recommends this brand for them. They have filled out, coats are shiny, overall health is better. They never get sick like they did on the more expensive brands that were suppose to be healthy for them. November 1, 2014
