Authority Dog and Cat Food

Give your pet balanced nutrition at every age and stage of life. Authority dog food and cat food is backed by decades of research and solution-focused formulas. Whether you prefer a grain-free formula, or if your pet does best on food with healthy grains, you'll find dry and canned food options with Authority. Our pet food contains omega fatty acids to help support healthy skin and coat, with no artificial colours, flavours, preservatives or chicken by product meal. With Authority dog food, cat food, pet treats and food toppers, PetSmart makes it easy to give them the nutrients they need - and the flavours they love.
