A pet’s food energizes them from the inside out, and NUTRO® clean recipes are simple, purposeful, and trustworthy – made of real, recognizable, Non-GMO ingredients†. Each of our Dry Dog Food recipes is clean, and the same is true for our NUTRO® Dry Cat recipes. But we have more work to do on all of our wet, treats and MAX® Cat products, and we won’t rest until choosing any of our products means choosing clean for your pet. NUTRO®. FEED CLEAN™.
