Breeds in the Working Group are large, powerful dogs bred for work and not as companions, and includes some of the world’s most ancient breeds, such as the Mastiff. These dogs were developed to assist humans in some capacity – including pulling sleds and carts, guarding flocks and homes, and protecting their families – and many of these breeds are still used as working dogs today. Breeds in the Working Group are known for their size, strength, and intelligence – and are not meant for the novice dog owner.
