Brand Story
Why Mainsource?
MainSource is grain-free done honestly. No wheat, no corn, no rice — just real lamb (as lamb meal) and potato, with the grain-free carbohydrates, Omega oils, taurine and antioxidants that a medium-to-large breed dog thrives on. From an everyday adult diet to a higher-protein puppy growth formula, it's a real grain-free spec — salmon-oil Omega-3, evening primrose for skin, a full vitamin and mineral mix — at a price that makes grain-free feeding realistic. MainSource — grain-free, the way it should be
