Should companion animals with kidney disease eat a lower protein diet


Animals with kidney disease or kidney dysfunction should not eat lower protein diets; as this commonly held belief is misleading. As long as the protein source in their diet is of high quality, such as white fish and eggs and easily digestible, it helps kidney function and overall body nutrition.

It is the lower quality, poorly digestible protein diets—soy and wheat gluten—that tax the kidneys, making them work harder in filtering and clearing metabolic waste products, water, and certain chemicals and drugs from the body.

It has also been shown that feeding a lower phosphorus diet slows the progression of kidney disease.  Anywhere from 7 to 18 mg per pound of a dog’s weight is considered a low phosphorus diet.  As some foods that are relatively high in phosphorus also provide high quality protein, they can still be fed in moderation, because they are important components of a healthy diet.
