Rated 4.8 out of 5 by 202 reviewers.
Rated 5 out of 5 by Excellent product My 18-month old black lab has been eating Science Diet since we brought him home at 8 weeks old. My previous dog ate Purina Beneful all his life and died of liver cancer, so after much research I decided I was never going that route again. Check out Reggie and how healthy he is!! He is 122 pounds of solid muscle, runs like a locomotive, and is so shiny black, he's blue. Love Hill's & Science Diet. Thank you for a healthy puppy. October 20, 2016
