Royal Canin Veterinary Diet Renal Support F Dry Dog Food is an easy to digest, savory meal designed to help dogs with kidney disease. Previously labeled as Veterinary Diet Renal LP Modified Dry Dog Food, this new and improved formulation has a greater aromatic profile and tempting texture to ensure superior palatability, and even more health benefits for your dog. By enhancing nutrients like B vitamins and the fatty acids EPA and DHA, and restricting others such as protein, phosphorus, and sodium, it slows down the development of kidney problems while minimizing uncomfortable symptoms.
