The Terceira Mastiff (Portuguese: Cão de Fila da Terceira) is an extinct Portuguese dog landrace, also known as the Rabo Torto (rabo=tail, torto=curled/twisted).^{[1][page needed]}

The Terceira Mastiff came from the island of Terceira, located in the Azores, which is the only island where this dog has ever existed and where it was employed as a house guardian. It descended from the Rafeiro do Alentejo.^[2]

In the 1960s, there was an attempt to revive the breed with the aid of the Portuguese government.^[1] However, there was disagreement between government officials and breeders, which led to the project's failure.^[1] After this, the future of the Terceira Mastiff depended solely on local farmers and breed fanciers. By the 1970s, it was already declared extinct.^[1]

It is an ancestor to both the Cão Fila de São Miguel and the Fila Brasileiro. This breed is different from the Barbado da Terceira.

The Terceira Mastiff is a medium-sized molosser that represents the Fila or Dogo type and resembles the Cão Fila de São Miguel. One of its most remarkable features is an innately short, corkscrew-like tail.^[1] Its nose can be either black, brown, or even pink.^{[citation needed]} The colour of the short, smooth^{[citation needed]} coat can be either fawn or yellow, always with a light mask.^[1] Red, black and brindle individuals are usually considered to be impure.^{[citation needed]} The height is approximately 55 cm (22 in).^[1]
