Choosing the right food for your dog can be a daunting task, especially when your furry friend has specific dietary needs. For dogs that require a low-protein diet, the selection process becomes even more critical. This comprehensive guide provides you with an in-depth understanding of low-protein dog food, its benefits, and the best options available in the market.
What is Low-Protein Dog Food?
Low-protein dog food is essentially dog food that has a lower protein content than standard adult dog food. Normal dog food usually contains at least 25% dietary protein on a dry matter basis. In contrast, low-protein dog food typically contains less than 20% dietary protein on a dry matter basis1.
Why Choose Low-Protein Dog Food?
A low-protein diet isn’t for every dog. In fact, it’s not for most dogs. Normal, healthy adult dogs do not need to be fed a low-protein dog food. However, there are certain medical conditions that need to be addressed with a low-protein diet2.
Medical Conditions That Benefit from Low-Protein Diets
“Dogs with chronic kidney disease and liver disease will benefit the most from a low-protein diet,” says Leslie Brooks, DVM and veterinary advisor at betterpet3. Dogs that develop bladder stones, called purine urolithiasis, whether or not they have underlying liver dysfunction, can also benefit from a low-protein diet to help the stones dissolve and prevent them from recurring4.

Dogs That Should Avoid a Low-Protein Diet
Growing puppies and pregnant or nursing dogs should not be fed a low-protein diet. This is because their nutrient requirements, especially for proteins, are in high demand during growth and reproduction. Limiting their protein intake could cause growth impairments and malnutrition5.
What to Look for in a Low-Protein Dog Food?
Low-protein dog food, as it is typically needed for management of kidney and liver disease, should also have added omega-3 fatty acids, antioxidants, Vitamin E, and Vitamin C in it. These help decrease the amount of free radicals and inflammation within the body and affected organs, and can improve quality of life6.
