Rated 4.7 out of 5 by 75 reviewers.
Rated 5 out of 5 great food for an active dog Our black lab is the center of our family. She is very caring and loving but she also uses up a lot of energy chasing squirrels, her boyfriend, tennis balls or whoever else crosses her path and plays with her. Her food was recommended by our vet and she is fit and very athletic. It was important to us that she does not gain weight excessively which can cause hip and joint problems later on. The food allows us to fill her up and then also spoil her with the occasional, ok daily, treat. When it is feeding time, she couldn't be happier. June 1, 2013
Rated 5 out of 5 by Science Diet Adult Large Breed Light my dog starting gaining some weight from lack of activity during winter, we switch to light he lost 5 lbs in 7 weeks, he is more playful again, and looks great. November 30, 2014
Rated 5 out of 5 by Science Diet Products are great I feed my 3 labrador retrievers Science Diet for Large Breed Dry dog food every morning. They love it. My chocolate lab would rather have the dry dog food than a can of dog food with meat in it. We go though a lot of bags of Science Diet for Large Breed Dry dog food in a month. Thanks for making a great product. May 17, 2012

Rated 5 out of 5 by This product has kept my dogs weight in check. Our English Lab has been using Science Diet for the past 3 years. He switched to Light because of weight issues.

Rated 4 out of 5 by Samson My St Bernard mix & Australian Shepherd eat this better than they do some others. May 16, 2012
Rated 5 out of 5 by I wouldn't feed my dogs and cat anything else!! I have tried many different types of science diet: advanced fitness, adult light and perfect weight. My dogs were eating perfect weight for a whole year to lose weight and my one dog lost a good amount of weight he went from 125 to now being around 102. Now that I have him at a healthier weight I feed them adult light and I've found when I would switch their food they'd have sensitive stomachs but with science diet I can switch to a different type of food that's science diet and they don't have those issues they were having with other brands. I suggest this brand to everyone I know with dogs/cats. I love it! It's worth the price! September 26, 2015
