Purina ONE Natural Chicken & Rice vs Purina ONE Chicken & Rice Dry Dog Food

These are the same Purina ONE Chicken & Rice adult formula in two bag sizes, so the food itself is a tie. Both use real chicken first, prebiotic fiber for gut health, omega-6 for skin and coat, and glucosamine for joints, and both hold a 4.7 rating from thousands of owners. The only real decision is bag size: the 31.1 lb bag suits one dog or a smaller household, while the 40 lb bag means fewer reorders and less chance of running out. Buy the size your dog finishes within about six weeks of opening, since kibble loses freshness once the bag is open.

• Choose the Purina ONE 31.1 lb bag if you have one dog or a smaller dog and want the food to stay fresh before it is finished.
• Choose the Purina ONE 40 lb bag if you have a large dog or more than one dog and want fewer reorders.
