Low protein foods are indicated for dogs suffering from chronic illnesses such as liver and kidney disease. It is also advocated for dogs with urate kidney stones. The kidney and the liver are involved in the metabolism of proteins and such diets reduce stress on the organs.
Low protein diets for dogs with chronic diseases as stated above are permanent and should be given continuously as the chronic illnesses are terminal. For cases of urate kidney stones, the diet is prescribed up until the condition has resolved and a normal diet should resume thereafter.
Low Protein diets contain half as much protein found in a normal diet. Treats should also be limited to one low protein ingredient. High-quality protein sources should be used to ensure dogs get their share of essential amino acids.
