Just like us, some dogs aren't at their very best when fed a grain-based diet. That's why OPTIMUM™, together with Dr Chris Brown, have scientifically formulated a Grain Free formulation. Providing your dog with a nutritionally complete and balanced food that is not only free from grains, but also high in protein with added essential vitamins and minerals. Meaning your dog can get more out of their food, to get more out of life.
