Royal Canin Veterinary Health Research Urinary S/O is a complete and balanced dry diet specifically formulated for adult dogs to support urinary tract health and manage the risk of stone formation. Urinary issues can be a significant concern for dogs, often leading to discomfort and recurring health problems. This specialised recipe is designed to create a bladder environment that is unfavourable for the development of both struvite and calcium oxalate crystals, providing essential nutritional support for your dog's long-term wellbeing.This formula utilises Relative Super Saturation (RSS) methodology to help lower the concentration of ions in the urine, which are the building blocks of painful stones. By promoting increased urine volume, the diet helps to effectively dilute excess minerals, ensuring they are flushed from the system more efficiently.
