Whether this is your dog’s first urinary issue or he has developed food sensitivities and needs ongoing urinary care, your vet recommended Royal Canin Urinary SO + Hydrolyzed Protein for a reason. This veterinary-exclusive dry dog food was developed to nutritionally support your adult dog’s urinary tract and bladder health. It’s designed with Relative SuperSaturation (RSS) methodology to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. It also features highly digestible hydrolyzed protein, which helps reduce the risk of stomach and skin signs in dogs with food sensitivities. Talk to your veterinarian about keeping your dog on this urinary dog food with Royal Canin Hydrolyzed Protein Treats for long-term urinary tract support.

Great Food!

My dog Everett was about 9 when he developed a chicken allergy! He lost a significant amount of his coat and licked nonstop! After trying so many different dry foods we finally sampled this! He is 15 never licks and has grown all his lost fur back! Thankyou so much!

It's the Best!

I was given a prescription for Royal Canin Urinary SO to prevent my dog from getting stones because crystals were found in her urine. My vet says it's the highest quality food. My dog's been eating it for 6 years now, and she's never had a problem. She's very healthy, so I would highly recommend it.

She likes it!

We had to switch to this formula after our pup got bladder stones. She likes it dry and soaked too, for some extra water intake. We get the big bag so as not to have to buy too often. It is a bit pricey.

Life Saving!!

Our dog had 3 Types of bladder crystals along with major bladder infection that almost took his life in a two day period! He was prescribed the SO formula at age 2. Now he is 6. Not a day without it since prescribed. No signs/symptoms EVER AGAIN! I will say it again, IT SAVED HIS LIFE!!! Thank you to the whole team at ROYAL CANIN!!!!
