HELPS PREVENT STONES: Specialized adult dog food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

WEIGHT MANAGEMENT: Low calorie dog food (11% less than Royal Canin Urinary SO Dry Dog Food) for ideal weight maintenance

BLADDER HEALTH: RSS methodology for dog bladder health helps lower the risk of crystal formation

S/O INDEX: The exclusive S/O Index creates an environment unfavorable to crystal formation in the bladder to help support urinary health

When your dog has urinary issues, easing their discomfort requires special care. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This veterinary-exclusive dry dog food was developed to nutritionally support your adult dog’s urinary tract and bladder health. It increases the amount of urine your dog produces to help dilute excess minerals that can cause crystals and stones. Moderate calorie content (11% less than Royal Canin Urinary SO dry dog food) helps them maintain a healthy weight. Relative Super Saturation (RSS) methodology is used 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. Lower urinary tract issues may be a recurring concern for some dogs. Talk to your veterinarian about keeping your dog on this urinary dog food for long-term urinary support. And ask them about the right Royal Canin wet dog food and treats to complement your dog’s diet.

Keeps pups healthy!

Our adorable Shih Tzu had bladder stones 4 years ago and he and his brother have been on this diet since. They love the kibble and have been very healthy pups!

Helped my dog...can help yours too!

My veterinarian recommended this product when my dog was having problems with her urinary tract. She hasn't had any problems since and it has had no affect on her digestive system. Very glad I use this product!

Keeps our dog both healthy and happy

We've been using this product for years now after 2 major $$$ surgeries for bladder stones for our Bichon Frise. We are so thrilled to have found a food that not only nourishes her, but also protects her from developing bladder stones. This food has been a life saver. Thanks, Royal Canin!

No more bladder stones!

My 4 year old springer spaniel mix was diagnosed with bladder stones after having an X-ray (done for bloody urine). We changed her dog food to RC Utinary SO mod calorie and her bladder stones went away in 1 month! She’s been great for 2 years on this food.
