Helps dissolve and prevent pure struvite stones and helps prevent calcium oxalate stones

Lowers the risk of crystal and stone formation using RSS methodology for bladder health

Highly palatable hydrolyzed proteins help to reduce skin and GI reactions that may be a result of food sensitivities to common proteins found in pet food

Supports healthy digestion and reinforces the skin barrier with nutrients to support and maintain healthy skin

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.

Health saver

My little girl had so many issues before I changed her diet to Royal Canin. After her surgery for bladder stones, our vet suggested the Urinaty Blend. This was 2 years ago and Things have been awesome. She is a happy little dad hind once again. I have no pictures because my little Hoku is pure black and very camera shy. I've tried so many times to no avail.

Recommended by our Vet and loved by our dog

I have been feeding this food to my dog for about two years. Since feeding her this food, she has not experienced any more problems with urinary crystals and seems to still enjoy the taste of this food.

Finally a food that my dog can and will eat!!

My dog has a multiple diagnosis, and is on a severely restricted diet. This is the first food that satisfies the requirements for both of his specialized diets, and that he will actually eat!!
