ROYAL CANIN® Canine Urinary S/O is specifically formulated with the nutritional needs of dogs with urinary sensitivities in mind. ROYAL CANIN® Canine Urinary S/O helps to dissolve all types of struvite stones that may form in your dog’s bladder.

ROYAL CANIN® Canine Urinary S/O’s exclusive complex helps to dilute your dog’s urine, making it less likely for calcium oxalate stones and struvite stones to form in the first place. Relative Super Saturation (RSS) methodology is utilised for the development of ROYAL CANIN® Canine Urinary S/O. RSS helps to lower the concentration of ion in your dog’s urine, minimising the likelihood of bladder stones forming. As magnesium is also a natural component of struvite crystals, ROYAL CANIN® Canine Urinary S/O is formulated with a reduced level of magnesium. 

As part of the ROYAL CANIN Veterinary Range, it is important that this product is only given to your pet when recommended by a veterinary professional.
