Dogs with chronic kidney, or renal, failure cannot recover. However, proper feeding may help prolong their lives. Avoid any high-protein, high-sodium or high-phosphorous foods that will task the kidneys. Along with safe foods, make sure a dog with chronic kidney failure is always well-hydrated. Before embarking on any dietary changes, check with your veterinarian to make sure they are safe for your dog.
Chicken and Potato Diet
For those who want to prepare their dog's own meals, "Home-Prepared Dog and Cat Diets, The Healthful Alternative" by veterinarian Donald R. Strombeck suggests a chicken and potato diet for dogs suffering from chronic renal failure. This low-protein, low-phosphorus, low-sodium and high-potassium diet includes 1/4 cup cooked chicken breast, 3 cups boiled potato with skin, 2 tbsp. chicken fat, 1 1/2 calcium carbonate tablets (600 mg calcium) and half of a multiple vitamin-mineral tablet. Check with the veterinarian to make sure this is appropriate for your dog.
Egg and Potato Diet
Strombeck also suggests a homemade egg and potato diet for dogs with chronic renal failure. This diet is low in sodium, phosphorous and protein while high in potassium. The recipe is: one large cooked egg; 3 cups potato, boiled with skin; 1 tbsp. chicken fat, 1 1/2 calcium carbonate tablets (600 mg calcium) and half of a multiple-mineral tablet. Check with the veterinarian to make sure this is appropriate for your dog.
Hill's Prescription Diet K/D
This food, available only from veterinarians, is formulated for dogs with kidney disease, which is the K/D in the name. It is low in phosphorus to help maintain kidney function in a dog in renal failure, and low in protein to keep kidney workload to a minimum. To help maintain blood pressure, the food is low-sodium. It includes additional B vitamins because those vitamins are lost in the urine in dogs with chronic renal failure. The food also contains omega-3 fatty acids to aid the kidneys and antioxidants for the immune system.
