Royal Canin Urinary S/O Dry Food for Small Dogs

Royal Canin Urinary S/O Small Dog is a vet-exclusive, complete dietetic dry food for adult small-breed dogs (under 10 kg). It’s specially Dry Dog Food formulated to dissolve struvite stones, reduce recurrence of struvite and calcium oxalate stones, and support general urinary tract health by:

  • Acidifying urine, which inhibits stone formation

  • Reducing magnesium levels and urinary ion concentration (low RSS)

  • Encouraging urine dilution to wash out crystal-forming minerals

  • Containing tartar-control nutrients, helping reduce plaque buildup on teeth

Key Benefits

  1. Struvite Dissolution: Actively dissolves existing struvite stones.

  2. Low RSS: Minimizes the concentration of minerals that cause both struvite and calcium oxalate crystals.

  3. Urine Dilution: Helps increase urine volume for better flushing of the urinary tract.

  4. Tartar Control: Ingredients that trap salivary calcium, reducing plaque and tartar buildup.

Feeding recommendation:
Royal Canin Veterinary Dog - Urinary S/O Small Dog is a complete dietetic food for small breed adult dogs.
