Rated 5 out of 5 by weight loss is for real this is the second dog i have been using science diet dry food, never a quality problem, my dog has enjoyed it from when he was 12 weeks old to now 12 years, he has a great shiny coat, November 11, 2015
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 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 Our dogs young and old love this food 15 free feeding dogs, large and small, all enjoy this food! We use 3-4 of the largest bags a week. Keeps our dogs healthy. February 5, 2014
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. Since the switch we have been able to keep his weight in check. We will continue to use this product as he ages. Thank you science diet for making such great products for our pet. May 16, 2012
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 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
