The Cão de Fila de São Miguel (frequently translated into English as the São Miguel Cattle Dog, but other names, such as Azores Cattle Dog, may be used) is a dog breed of molosser 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 for working with cattle. 

History

The breed is named for São Miguel Island in the Azores, settled by the Portuguese, beginning in 1439. Another of the Azores, Terceira Island, is known for bullfights and cattle raising; large dogs used on cattle there were brought to São Miguel Island and contributed to the development of the breed. According to the original breed standard, the existence of the Cão de Fila de São Miguel has been documented since the early 1800s. A breed standard was developed in the breed's area of origin and first published in 1984. This standard was recognised internationally in 1995, when the standard was published by the FCI. Although described (and formerly used) as a cattle dog, the Cão Fila de São Miguel is actually a molosser, and is so recognised by the FCI in Group 2, Section 2, Molossoid breeds (number 340.) Today it is primarily used as a guard dog and companion. Traditionally, the tail is docked, although this practice is now illegal in many areas. In addition, the ears were traditionally cropped short; cropped ears are characteristic of dogs used for fighting.  The ears are cropped short and rounded off on top. The reasons for these traditions are unknown. Literature about the breed warns that they can be very aggressive, a characteristic said to be valuable in handling feral cattle, but potentially dangerous in a pet. Today, dogs from São Miguel are exported to North America and other areas of the world where they are bred and promoted for the rare breed market. Minor kennel clubs and registries maintained by individual breeders write their own versions of the breed standard, which may vary from the breed standard developed on the island of São Miguel and recognised internationally by the FCI. Dogs of the breed may be sold under the original breed name, Cão de Fila de São Miguel, or any of the many translations and versions of the name. 

Appearance and Size

A large dog, but not oversize; 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. Ears are drop 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. 

Personality

A large, aggressive, working dog, the Cão de Fila de São Miguel must be well socialized at an early age if it is to be kept as a pet, and supervised when around unfamiliar children.  As with all working dogs, it must be given regular training and a job to do. Temperaments of individual dogs may vary greatly. Suitability of an individual dog for a particular kind of work may depend on the quality of early training.
