  • Great Treat

    By on

    Was thrilled to find that Chewy carried large bags of Hills Science Diet Oral Care. This is the only Treats my Bichons get. As soon as I ask if they want a "cookie" they are ready to run and find. Not only is it nutritional, it is good for their teeth as the size requires they chew each piece.

  • Picky eater.

    By on

    First I love the selection offered at Chewy. The quick delivery is fantastic and so are the prices. My dog is a very picky eater and he love the Hills Science diet. I also get treats for him and I am pleased that his favorites are made in America.

  • Gives them something to get their teeth in

    By on

    Large, fibrous chunks made with chicken and rice. The dogs like it. Don't really see any dental benefit but it's a great addition to a balanced diet of home-cooked meat and veg.

  • My 18 pound Pomeranian loves this food

    By on

    My Pom was a rescue and has horrible teeth. He gets his annual teeth cleaning every February. My Vet suggested I try Product for him and go into your website. I first bought a small bag at a local pet store and my Pom loved it!! So I ordered larger bag and will eventually do the automatic shipping as soon as I know how long if takes to go through the food. Thanks for making things easy and saving !!

  • My dog is FINALLY chewing his food!!

    By on

    I'm not thrilled with the ingredients compared to his last food. BUT this was for his dental health and to get him to actually chew his food and not swallow it all whole. The large kibbles entice him to chew each one which cleans his teeth. And he seems to love the flavor. He gets very excited for meal time now.

    Been using these very large oral care kibble for my dog's for years. About 10 with each meal plus regular food makes mealtime interesting for the puppies. Help keep teeth clean too.
