The Saint Miguel Cattle Dog (Portuguese: cão fila de São Miguel [ˈkɐ̃w ˈfilɐ ðɨ ˈsɐ̃w miˈɣɛl], literally 'catch dog of São Miguel') is a dog breed of mastiff type originating on São Miguel Island in the Azores, an island chain which is one of the autonomous regions of Portugal. The breed was originally used as a herding dog for working with cattle. The breed is large but not over-sized; up to a maximum of 60 cm (23.6 ins) at the withers and 35 kg (77 lbs) in weight, with females slightly smaller. The general appearance is of a normally proportioned, deep chested, muscular dog with a broad head and medium length neck, straight back, and long legs. The tail is held up and is slightly curved. The breed has drop ears, unless they are cropped. The coat is a brindle of brown (pale brown is described as fawn) or grey, with black; it is short, smooth and harsh to the touch, with a short fringe on the tail (if undocked) and on the backs of the rear legs.
