Renal failure in dogs is no different than in humans. This condition is characterized by the inability of the kidneys to perform their functions properly. The kidneys rid the body of toxins. The waste produced by the kidneys is extracted from the body through urine. Symptoms include vomiting, weight loss, fatigue and tremors. It is a chronically progressive disease that is irreversible and inevitably fatal.

Increase Protein Intake
-
It's assumed that removing proteins from your dog's diet would be a perfect cure for kidney disease. When the body digests protein, it produces toxins that are excreted by the kidneys. So cutting proteins would eliminate this process altogether. The truth is that your dog's daily protein requirements increase slightly when his kidneys begin to fail. Removing or limiting protein can cause protein malnutrition. Commercial pet foods formulated for animals with renal failure, such as K/D Prescription Diet, offer high-quality protein in measured amounts. This food also provides your dog with the appropriate amount of calories she needs from non-protein foods.
Fiber
-
Iams, one of the leading pet food manufacturers, found that food sources with fermentable fiber can help kidney function because it utilizes the colon, rather than the kidneys, to rid the body of toxins. By formulating a food excreted via feces, as opposed to urine, a dog living with kidney disease can consume and absorb the nutrients she needs without further damaging the kidneys. Iams suggest its Veterinary Formulas brand dog food, which has the recommended ratio of five to one Omega-6 and Omega-3 fatty acids.
Preparing Your Own Food
-
It's hard enough deciphering the ingredient labels on food you buy for yourself. Pet foods do not have the same dietary disclosure laws. So if your pet has renal failure, and you want to be absolutely sure he's getting all the nutrients he needs, don't hesitate to reach into your pantry to prepare her meals. For high-quality protein, mix egg whites in with lightly cooked meat and rice. Limit the amount of yolks in your dog's diet since they contain high levels of phosphorus -- a mineral that can worsen kidney disease. Raw and lightly cooked meats high in fat like hamburger, lamb, pork and dark chicken and turkey are best. Some raw and blended fruits like apples, avocado and bananas, are good for dogs with renal disease. Feed these foods sparingly if they cause loose stools. White rice and pasta with small amounts of butter are also good sources of protein (for some recipe ideas, see Resources). And avoid processed meats, like those found in the deli section, since they have the lowest levels of quality protein.
