Keep my dogs in good shape I tried to go to other foods but came back to the Light. They love it and its great on the digestive track. October 16, 2013
Great for a dog that needs to lose weight Two years ago, my lab retriever was overweight by 20lbs. My vet recommended Hill's science diet and it really helped with my dog losing the weight. Matter of fact, between his food and exercise, he lost all the weight and more. I like the fact that his food is lower in fat and it's not made of all those artificial ingredients. I do wish it was less expensive or maybe more coupons could be offered. But I do think that if you want a quality product, you can't go wrong with this. September 26, 2013
Been feeding my/our dogs this since 1969. We have had several labs and some mixed breed rescue dogs. All have been fed Science Diet. Currently, my dog who is allergic to grain (smaller lab rescue) enjoys Hill's Ideal Balance. My last lab (mix) lived to be 16 years, 10 months. I wouldn't feed my dogs anything else.

works wonderfully I have 3 dogs and weight control has been an issue. I have tried numerous weight management brands but to no avail. My vet suggested Since diet. I originally put my dogs on the metabolic till the weight came down then changed to the light. My dogs love this and the weight is being maintained. Thank you so much for this product. Keep up the good work September 24, 2014
Lots of Fiber Altho my dogs - two - are 10 years old, I like the high fiber content of this product. I started using it when one of my dogs had loose bowel movements. Vet said to use the Light Science Diet for a while because it had a high fiber content. Since I have 90 pound dogs, I found the Large Breed bags with both high fiber/ light content was good for my dogs. They are both on a regular schedule, and I truly believe look better and feel better. Wouldn't buy anything else, altho sometimes it's hard to find. Then, I just buy the Light bag. September 22, 2014
Helps keep my dog's coat healthy My dog's coat is soft and healthy. She is 6 years and people cannot believe how soft her coat is. I believe it is due to Hill's Science Diet dog food. September 13, 2014
