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 NUTRO™ Dry Dog Food recipes is clean, and the same is true for our NUTRO™ Wet Dog recipes, NUTRO™ Dry Cat recipes, and NUTRO™ Crunchy Treats. We are pleased to announce that our ULTRA™ Wet Dog recipes will soon be clean and look forward to officially adding it to the list of clean recipes. But we have more work to do on all of our wet cat food, all other dog 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™. Manufactured by Mars Incorporated.
