HELPS DISSOLVE STONES: Innovative urinary tract dog food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

BLADDER HEALTH: Lowers the risk of crystal formation using RSS methodology for dog bladder health

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

SPECIALIZED KIBBLE: Adapted kibble size for small dogs encourages chewing to help reduce tartar buildup

When your small dog has big 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 small 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. Low 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. And for dental health, the adapted kibble size for small dogs encourages chewing to help reduce tartar buildup. 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 treats to complement your dog’s diet.

Great Food

My little dogs love the prescription urinary so as they have had bladder stones and one of them it has been used as preventative and has work great. I also use the canned version with the dry but they love this food and wished I could buy it for my big dogs but due to the cost I am unable to afford it for them as well since my Newfie eats 5 cups of food a day.
