The mastiff is a large dog ideally suited for use as a guard dog. Mastiffs are one of the larger dog breeds in existence and are distinguished by a large powerful body, a wide head, a limited range of coloring and a black mask. They are gentle dogs, but alert and fiercely protective of their group, making them highly prized and valuable companions for humans. Descended from the Alaunt group of dogs, the original mastiffs were from Britain and known as the English Mastiff.
