Give your dog balanced nutrition at every age and stage of life. Authority dog food is backed by decades of research and solution-focused formulas. Whether you prefer a grain-free formula, or if your dog does best on food with healthy grains, you'll find dry and canned food options with Authority. 

Authority dog food contains omega fatty acids to help support healthy skin and coat, with no artificial colors, flavors, preservatives or chicken by product meal. With Authority dog food, PetSmart makes it easy to give them the nutrients they need - and the flavors they love.
