Purina Pro Plan Veterinary Diets NF Kidney Function is a prescription wet dog food sold as 24 x 377g cans and formulated for adult and ageing dogs with chronic kidney disease. It's designed to be used under veterinary supervision as part of long-term management for dogs diagnosed with renal dysfunction.

The formula is made with a restricted amount of high-quality protein and restricted phosphorus — two of the most important dietary adjustments for managing chronic kidney disease in dogs. By lowering the workload on compromised kidneys while still providing adequate nutrition, this diet helps slow the progression of the disease and can improve quality of life for affected dogs. The wet format is particularly useful for kidney patients because it adds moisture, supporting hydration — an important factor for dogs with renal conditions.

Dietary management is one of the most important things owners can do for a dog with kidney disease. Wet formulas like this one are often better tolerated by dogs with reduced appetites — a common issue in renal patients — making them essential for keeping dogs eating and maintaining body condition during management.
