Royal Canin Canine Urinary SO 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. 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 this specialized nutrition, with a reduced level of magnesium, helps dissolve pure struvite stones and prevent struvite stones from forming. 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.
