Why Senior Dog Food?


As dogs age, they start to slow down—both physically and mentally. Their nutritional needs change, too.  


Around age seven (later for some smaller breeds) is when a food for older dogs becomes important.  


Finding the best senior dog food for your companion is an important way to help them continue to live a happy, healthy life. Purina offers a variety of dog foods for older dogs, each specially formulated to nourish them through their senior years.  


Like the best food for older dogs should, each of our senior dog diets helps to maintain a senior dog’s health, even as they age.
