Our take on the Purina ONE Grain Free Natural High Protein Dog Food Formula True Instinct with Real Beef with Added Vitamins, Minerals and Nutrients, 6 lb.

Purina ONE True Instinct Grain Free with Real Beef is a dry adult dog food built around beef as the first ingredient, with 30% protein and no corn, wheat or grains. It adds glucosamine for joints, omega-6 for skin and coat, and calcium with crunchy kibble for teeth and gums. It suits owners who want a grain-free, high-protein kibble from a large mainstream brand without moving to a premium-priced line. Against grain-inclusive Purina ONE formulas it trades grains for more meat-based protein; against boutique grain-free brands it is widely available and broadly liked, though some owners report digestive upset when switching and picky dogs refusing it.
