ROYAL CANIN® Urinary S/O Small Dog Dry 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.
