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.

Great product!

My dog has been on this food for so long I don't even remember, at least 10 years. She is not 15 and very healthy for her age. She has had no more urinary/bladder issues since she has been on this food. She literally gobbles it up within seconds at every feeding, still after all these years on the same food!

Bella Gobbles It Down Fast!

We rescued Bella and she was very ill. The Vet recommended that we feed her RC SO dog food. She perked right up and has been eating it for about six years now.

No more crystals

This has really helped with Sadie's crystals. Bichon's tend to have this problem. And that is what my Baby is. Crystal free.
