It uses real chicken as the primary protein source, providing a high-protein formula suitable for adult dogs of all breeds. This combination supports muscle health and energy maintenance. The recipe includes rice, making it grain-inclusive rather than grain-free, which can be easier for some dogs to digest and is often a more affordable option.
