Product Description

Cystine stones (uroliths) occur when an inherited defect of the kidneys causes a build up of cystine in the dog’s urine. Cystine is an amino acid that is filtered and reabsorbed by the kidneys. The build up of this amino acid in the urine leads to the formation of cystine stones. Certain breeds are more affected than others by cystine urolithiasis. These include English Bulldogs, Newfoundlands, Dachshunds, Chihuahuas, and Mastiffs. Mixed breed dogs with the ancestry of these genetically susceptible breeds can also be affected.

Key Benefits

  • Low purine proteins combined with the production of alkaline urine help reduce the risk of urate stones
  • Moderate quantities of high quality proteins and controlled methionine and cystine levels
  • Enhanced levels of linoleic acid, zinc, and biotin help to promote a healthy skin and shiny coat
  • Naturally preserved to ensure freshness and quality

NOTE: Royal Canin veterinary diets require a veterinary prescription. This product will not be shipped until a copy of a valid prescription authorization is faxed to 1-800-619-7973 or e-mailed to

Customer Ratings & Reviews

Rated 4.8 out of 5 by 10 reviewers.
Rated 5 out of 5 by refined dog food. Thank you for doing research on behalf of my Dalmations. My Vet recognised the problem and prescribed Pills to oblivate the condition. Your dog food is his maintence and thanks to you all my dogs are well. November 20, 2014
Rated 5 out of 5 by A very needed product Ordering from was so easy and everyone was so helpful. Ordering from chewy wasn't just about the food. Of course my dog needs a certain food product for health reasons and the price was great at chewy(kudos!). When I looked at the website it became apparent to me that this company cares. My dogs are my everything - like so many other owners of fur babies - so I need to see know and feel like we are being taken care of and that the employees really do care about animals. We weren't just another sale or ticket. Thanks Chewy! July 9, 2015
Rated 5 out of 5 by Hassle free prescription This a RX only dog food. Chewy has a better price and hassle free buying. So much easier than a trip to the vet and less expensive too. January 1, 2015
Rated 4 out of 5 by Royal Canin Veterinary Diet Urinary UC Low Purine My dog was put on this after 2 surgeries to remove stones.. 13 the 1st time, 16 the 2nd.. So far 6 months in, this seems to be controlling it. I think it is a bit expensive, but not as expensive as another surgery.. September 3, 2013
Rated 5 out of 5 by Palatable! I couldn't have been more pleased when I needed to switch my dog over to veterinary feed. He has found this kibble to be very palatable and it has so far been effective in preventing more cystines from forming. December 22, 2014
Rated 5 out of 5 by Excellent food My dog has required two surgeries for bladder stones because he does not process purine well. He loves this food and eats every piece of it and often begs for more. It is easy for him to digest and he has had more frequent bowel movements with much less straining and discomfort than with his previous prescription food. He hasn't been on it long enough to know if it helping prevent stone formation, but I'm keeping my fingers crossed. December 10, 2014
Rated 5 out of 5 by Awesome I'm a very satisfied and happy first time customer!!! Awesome product! Awesome prices! Awesome service! Very happy with!! July 7, 2015

Thank you You are the best! May 31, 2013
