Focus on nutrition: Nutritional management of protein-losing nephropathy in dogs

Optimal treatment of protein-losing nephropathy (PLN) should address both medical and nutritional issues. In nonazotemic dogs with PLN, the main nutrients of concern are protein, calories, omega-3 fatty acids, and sodium. In azotemic dogs with PLN, requirements for additional nutrients should be addressed. The amount of protein and the specific diet must be individualized for every patient with PLN because commercial dog foods differ greatly in protein and other nutrients. It is critical to avoid excessive dietary protein restriction, which may contribute to loss of lean body mass. A thorough diet history must be obtained to account for the animal's entire daily intake of protein and other nutrients.
