  • So Great, Just Wish Resealable

    By on

    My dog loves the Hill's Science Diet line, just wish that the product I received was resealable as the image implied! I've tried the small bag, I've tried the big bag, and neither from Chewy.com so far seals.

  • Great for my picky eater

    By on

    My rescue dog came to me pretty emaciated and showing little interest in food (even the dog chow she was fed at the shelter). I initially started her on the Chicken and Barley formula, but she wasn't very interested. I decided to try the lamb meal and rice formula before trying another brand, and my picky eater has come around. She's still not like some dogs who barely come up for air once their dish is filled, but she has been eating it consistently and waits by her dish with expectant eyes when she's hungry and will dive right in once fed.

  • Always reliable!

    By on

    My cat has grown old and is remarkably healthy because of Science Diet, now my dog will too! Some people don't trust non-boutique brands but Science Diet DOES THIER RESEARCH. Plus my dog loves the lamb. It is very easy on her stomach and her coat looks amazing.

    So far, our 2 year old lab is doing well on this Lamb & Rice. She is still somewhat itchy, but I think she always will be. It seems to be eliminating the dandruff that the vet diet foods cause. (Lots of allergies with her)

  • Hill's Science Diet (American Made )

    Service is Great. Pricing is fair. Except- Should be priced for returned customers instead of just auto-reorder customers. Only buy American Made products.

    My picky eater loved this dry food. I typically mix it with a half can of wet food and he devours it all.
