About Royal Canin Urinary Health for Dogs

Royal Canin, incredible in every detail.  Tailored nutritional solutions for urinary health.

Worried About Your Dog’s Urinary Health?

Your veterinarian is the expert on your dog’s health, so you should always consult with this trusted advisor to find the best urinary health solutions for your pet. Royal Canin works closely with veterinarians to develop dog formulas that support urinary tract and bladder health.

How Can Nutrition Help?

Your veterinarian may recommend a Royal Canin Urinary formula for your dog. These special formulations can:

Dilute Urine

This helps your dog urinate more often, which can help minimize time for stones to form.

Lower RSS

RSS methodology predicts urine crystallization and is used to develop diets that reduce the risk of stone formation.

Maintain Balance

A precise mineral balance can also help prevent stones from forming.

Set Up Autoship for Consistent Delivery

Last-minute dietary changes can sometimes upset your pet’s stomach. Set your Royal Canin pet food order to Autoship to keep feeding on track and avoid unwanted disruptions.

About Royal Canin

What sets Royal Canin apart is their close collaboration with veterinarians. Through these professional partnerships, they strive to learn everything they can about pet health, including how different formulas perform for different breeds, sizes, lifestyles and therapeutic conditions. Ongoing research and development allows Royal Canin to keep providing the precise nutrition dogs need for a range of medical conditions.

Low Purine Diet

I have to Dals and one had problems with stones in the past, which ended up in $2000+ of vet bills. I wish I had found this diet sooner. It’s more expensive, but if your breed is prone to stones and you haven’t done the genetic testing, just get your vet to put them on this diet. Putting a vet approval on a diet is super easy here on Chewy.

My dog loves this!

My girl had struvite stones, so we had to go to a UI food. I bought the cheapest one, she would not eat it. She started skipping meals. I knew I had to do something,

My girl had struvite stones, so we had to go to a UI food. I bought the cheapest one, she would not eat it. She started skipping meals. I knew I had to do something, so I changed her to the Royal Canine version. I like that it comes vacuum sealed. The minute I put it in her bowl, she went after it. She was even trying to get into the container I keep it in to eat more. She is a happy girl now!

Our 8 month old Pyrenees ended up with stones and an expensive surgery. He used to be super picky and would graze with his food. Since putting him on this he scarfs it down and is excited for every meal! So far, no more stones either.

First time using Chewy. It was easy to locate this new prescription product for my Corgi. He's been experiencing urinary tract infections and stones. Scanning and uploading the prescription was a breeze, and the big bag of this kibble came quick. Right now, we're just waiting to see if this new diet is right for him.

Max’s prescription food

Max is no longer with us and we miss him terribly. He succumbed to his illness on September 11, 2025. But in 2023 when he suffered from severe urinary bladder stones

Max is no longer with us and we miss him terribly. He succumbed to his illness on September 11, 2025. But in 2023 when he suffered from severe urinary bladder stones (which I’d never heard of) Chewy came right out of the gate with his prescription Royal Canin and to my relief Max’s dad Huck ate it up too.
