ROYAL CANIN® Canine Urinary SO Moderate Calorie 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.

Struvite Dissolution
Urinary S/O Moderate Calorie effectively dissolves struvite uroliths.

Moderate Calorie
The reduced calorie content of the diet makes it possible to limit weight gain in cats with a tendency to obesity.

Urine Dilution
Diluting urine decreases the urinary concentration of struvites and calcium oxalates. The larger urinary volume also ensures regular bladder wash-out.

Low RSS
Undersaturated urine is an environment where crystals cannot proliferate. Thus the urine is unfavourable to the development of struvite and calcium oxalate crystals.
