    After my new vet recommended I give my four dogs the Hills Science diet prescription t/d dental food for treats I decided to feed this non prescription oral care formula along with their regular kibble. It has worked wonders on the 6 & 9 year old mini aussies mouths and has kept my year old min pin mix's teeth and breath pristine. They all love it. I feed my GSD the mix along with a larger regular kibble and it has made a difference in his teeth and breath. Very happy with this product all the dogs devour the large airy pieces and it slows down their eating. Now I can brush less frequently and the results are far better.

    Some years back I had to have 5 teeth out, due to eating snacks from the catbox and other , er-r-r less than tidy habits. My vet did a pro cleaning and told my person to get me "Hill's Science Diet Oral Care ." Since I started these delicious nuggets, I have not had any dental difficulties, plus I really love the way they taste, so when I get them, I think I am a "Good Girl," and getting a treat! Try them.

  • Not a hit for my Dorkie

    By on

    My dachshund yorkie mix isn't a fan of this food. He needs to keep better care of what few teeth he has left and he thinks this food is too hard to chew. The vet wanted me to give this diet a try since brushing alone isn't doing the trick. Guess I'll just have to brush more often.

  • Hill's Science Diet Adult Oral Care Dry Dog Food

    This food is my dogs favorite. She is a small breed dog and if I feed her only small bites, she ends up with a lot of plaque build up on her teeth. As soon as I start feeding her this type her teeth have become nice and clean again. It is one type offered from Science Diet that I can't always find at my local stores, so I'm happy Chewy offers it at a reasonable price. I will definitively be buying it from Chewy.

  • Great for teeth

    Our dogs love this food. Wenmox it in with their regular food and they always pick these kibbles out first. We also use it as their treats. It has helped keep our small dogs’s teeth clean so she does not have to have a dental cleaning!

    This food is a very good oral care food. My problem with our dogs is small mouths. This is large food and they could not bite it. Science Diet needs to have a SMALL BITES in this brand. Would be excellent for large breed dogs

  • Not for small dogs

    Bought this to help my 16 pound yorkie clean her teeth. The kibble is too large for her so we cut it up as a teeth cleaning snack. She does like it and her breath is better

  • Large dogs only

    By on

    I did not notice this food was apparently for large dogs. The bits are so big I have to crush them for my dog to be able to eat. Yuck.... Now I'm stuck with a large bag of large bits for more than a month.
