Product Reviews
Royal Canin Veterinary Diet ® Canine Urinary UC Low Purine dry dog food 18 lb bag is rated 4.9 out of 5 by 29.
Rated 5 out of 5 by from i bought this per my vet 5 weeks ago and ..... my do loves it. Sadly i had to throw out 1/3 the bag because the bag is designed for large bread dogs and my dog is only 15 pounds. The product is perfect other then the packaging and sadly it seems to be an issue that my vet faces all the time. It is so disheartening to find a prescription diet that my dog loves and will help keep him healthy and I can not buy it for him on a regular basis since I have no way to use it fast enough. If you are lucky enough to have a large breed dog with crystals this is the perfect food and i would recommend it any day. If you have a small bread dog I can unless like me you are willing to waste 1/3 of the bag.

Rated 5 out of 5 by from They love it and it works! We have been using this since our dog developed bladder stones several years ago-no problems since!

Rated 5 out of 5 by from Great Food! My boxer Oden has an ongoing condition that causes him to be on this food for life. He loves the taste and it is a very healthy product. It comes highly recommended from our vets. My boxer has had no problems and has been on the food for 2 years. I wish I could find it somewhere more affordable than $60.00 a bag though.

Rated 5 out of 5 by from My Dog Has Never Been Happier! I’ve been feeding my Dalmatian this low purine diet for about two years ago after learning he had bladder stones and was constantly licking his groin are due to discomfort and suffering from recurring secondary UTIs. I now recheck his urinalysis twice a year and he hasn’t had a single infection, his stones are well managed, and he’s no longer uncomfortable. His coat looks great (we constantly get compliments on how soft he is!) and he’s a perfect, healthy weight! We couldn’t be happier!
