When your dog has urinary sensitivities, the benefits of a specifically tailored diet can help to support normal and healthy urinary function. Specially formulated with the nutritional needs of your dog in mind, Royal Canin Canine Urinary S/O Loaf is only available in a 410g can. Your dog's urine contains a component known as struvite. Though this is a normal component, it can form as crystals or stones if the urine is too concentrated. The nutrients included in Royal Canin Canine Urinary S/O Loaf help to manage and prevent these issues. Royal Canin Urinary Support is a specially formulated diet for dogs in cases of bacterial cystitis, dissolution of struvite uroliths or calcium oxolate urolithiasis. The diet contains a carefully selected blend of ingredients to help manage symptoms and reduce discomfort, including increased levels of sodium to reduce the concentration of calcium oxalates and struvites and thus dilute urine. Magnesium levels are also reduced in the diet as magnesium is a component of struvite uroliths which exacerbate urinary complaints. A palatable and nutritionally tailored diet to suit even the fussiest canine appetites.
