Royal Canin Urinary SO Small Dog is a veterinary-exclusive dry dog food, developed to nutritionally support your small dogs 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.

This food requires a veterinary prescription.
