About Royal Canin Urinary Health for Dogs

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 dog food formula for your best friend. 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.

Great, But no other options, really!

We’ve been feeding this UC formula to our Olde English Bulldogge since he had emerg. bladder surgery for bladder stones and cysteine crystals (to save his life!) back when he was 2 y/o. He is now 8 and is doing great! We had to try the Hills version when there was a back order on RC, and he didn’t like it much. It’s scary that these two options are the only ones out there, though. Always buy a backup bag, just in case!

Big nuggets

This UC dog food has big nuggets compared to my glycol balance and I’m noticing I have to switch my auto ship to every 2 weeks and not three because by the third week we are out of food. I’m not happy that I have to spend 85$ bucks every 2 weeks. Instead of three .

Royal Canin to the rescue

Having two bulldogs with very specific dietary needs is always a challenge. When Hills Science Diet changed their formula my dogs had a bad reaction. I am so glad to have Royal Canin to try. So far - so good.

More please!!!

Barney a 3 year English Bulldog had to change from his Blue Buffalo food to a Urinary diet. Royal Canin came to the rescue with a food that meets his needs and he loves it!! Chewy was more than helpful in getting the new food to me within 24 hours and recommending a few treats. Their customer service is the best I have ever had to deal with. And, thank you Royal Canin for not only being one of the few mfgs. that make a urinary food but also a very good one!!

Feeling Better right away.

Kai was diagnosed with "crystals" in his urine. He was having trouble with urinary frequency. He was refusing to eat his food, so he was given a prescription for Royal Canin Veterinary Diet Urinary UC Dry Dog FoodRoyal Canin Veterinary Diet Urinary UC Dry Dog Food, since starting his special food, he is excited to eat again, he is doing much better with his potty habits and seems to be doing better. I'll do further tests on his diagnosis in a few months. Chewy was very responsive (I wish my emergency vet had been more cooperative in sending the prescription in) on getting my dog his food quickly, I was able to go to the Vet's clinic after an emergency visit after the weekend, I snapped a picture of the prescription and immediately emailed it to Chewy. We had the food in the next day. Thank you Chewy!

was prescribed by my Vet

It seems to be working well. I also notice that my dogs do not go poop as often so it appears they are retaining the nutrients
