The most important thing to do when supporting kidney health is to keep your dog as hydrated as possible. Since at Rick's we use all-natural whole foods in our diets, our foods contain high amounts of moisture especially our Kidney Support Diet. Also, every ingredient chosen for this formulation helps benefit the kidneys and help to reduce toxins in the body. Since our foods are human-grade they are much easier for the body to process and eases the entire digestion process. This helps reduce the strain on the kidneys. If you have a specific question about your pet's condition please give us a call at 407-505-2839 to discuss or simply stop by the Deli.
