Product Description

Product Overview

Royal Canin Urinary S/O Veterinary Dry Dog Food – 2kg is a complete dietetic food for adult dogs, specifically formulated to support dogs with urinary sensitivities under veterinary supervision.

The formula is designed for the dissolution of struvite stones and to help reduce the risk of struvite stone recurrence. Its nutritional approach includes low RSS (Relative Supersaturation), urine dilution and controlled mineral levels to create a urinary environment less favourable to the formation of struvite and calcium oxalate crystals.

Royal Canin Urinary S/O also contains a reduced magnesium level, as magnesium is a natural component of struvite crystals. Controlled levels of magnesium, calcium and phosphorus, together with urine-acidifying nutritional properties, form part of its veterinary urinary-support formulation.

Because this is part of the Royal Canin Veterinary Nutrition range, it should be fed only when recommended by a veterinarian.
