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 Donald R. Strombeck, DVM suggests a chicken and potato diet for dogs suffering from chronic renal failure. This low protein, low low phosphorus, low sodium and high potassium diet includes "1/4 cup cooked chicken breast, 3 cups boiled potato with skin, 2 tablespoons chicken fat, 1 1/2 calcium carbonate tablets (600 milligrams calcium) along with half of a multiple vitamin-mineral tablet." Check with the veterinarian to make sure this is appropriate for your dog.
Egg and Potato Diet
"Home-prepared Dog and Cat Diets, The Healthful Alternative" by Donald R. Strombeck, DVM also rnsuggests a home-made 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 tablespoon chicken fat, 1 1/2 calcium carbonate tablets (600 milligrams 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 phosphorus to help maintain kidney function in a dog in renal failure, and low 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. It also contains Omega-3 fatty acids to aid the kidneys and anti-oxidants for the immune system.
