I love that Hills Science Diet has products designed for specific needs! I love that Hills Science Diet has products designed for specific needs, and are formulated to help pets achieve their ideal health and weight requirements. My dog loves the flavor (he hasn't liked some other brands), and I love knowing that he is getting the best food for his age and overall health. September 19, 2013
If dogs could talk ---- Jesse James would tell me not to bother buying another brand. I've tried. After he wakes up in the AM he runs to his bowl - which is empty or I'd never get him out to do his morning duty - but he hurries because he knows what I'm now putting in his bowl. My sister's dog visits and the first thing Daisy does is run to Jesse's bowl. I have never had Jess stay loyal and look forward to eating dry food but this is a true winner and keeper. Thank you Hill's!! June 29, 2013
Best product for digestive issues I have been feeding my 3 year old lab pip science diet since a puppy. She had many problems as a puppy, digestive issues, parasites, loose stool. Vet put her on science diet and everything cleared up and I have had no problems since. I am a devoted science diet dog food buyer. If a pet store is out I go to another to get exactly what she needs. Her coat is as shiny as can be and she has grown into a beautiful black lab. I highly reccomend to friends who get puppies. Keep up the great news. May 29, 2013
Great Product My dog loves Science Diet. I am happy to find a dog food that my dog enjoys, and that I know is healthy for him. We use the adult dry food, but I plan to try some of the wet food for him very soon. Thanks for a great product! September 11, 2014

This is a must have pet food. Before I picked up my German Shepherd from the Humane Society, she had lived with cruel previous owners. We took her to the same veterinarian that her previous owners took her to, and he said they nearly broke her leg. He says they did this because they fed her second rate dog food, and she had an accident in the house. She couldn't help it at all, but they still hurt her. When we first got her, she was extremely hand shy, and seemed really happy every time we fed her throughout the day. She loves her dry dog food, and loves it even more when I mix treats sparingly in it. Though the price for the large bag of dog food is a bit high, I feel good knowing Hill's Pet donates to Humane Societies regularly. This is a good dog food at a good value, and now that we have a kitten as well, he is on the Science Diet also. I highly recommend this brand to anyone with a furry friend. August 6, 2014
