The Terceira Mastiff is a large dog breed that is native to the island of Terceira in the Azores archipelago. The breed is believed to be descended from the ancient Molosser dogs of Greece and Rome. The Terceira Mastiff was once a popular breed on the island, but it became nearly extinct in the 20th century. The breed was saved from extinction by a few dedicated breeders who began to promote the breed in the 21st century. The Terceira Mastiff is now recognized as a distinct breed by several kennel clubs.

The history of the Terceira Mastiff dog is shrouded in mystery. The exact origins of the breed are unknown, but it is believed to be descended from the ancient Molosser dogs of Greece and Rome. The first recorded mention of the Terceira Mastiff was in a 14th century document from Portugal, which described a large dog with short hair that was used for hunting on the island of Terceira. It is unclear how long the breed existed on the island before becoming nearly extinct in the 20th century.

The Terceira Mastiff became nearly extinct in the 20th century due to a combination of factors. First, many of the dogs were killed during World War II when American troops occupied the Azores islands. Second, there was a general decline in interest in large breeds such as mastiffs during this time period. Finally, many of the remaining dogs were killed during an outbreak of rabies on Terceira Island in 1954. By 1960, there were only two known surviving members of the breed: a male and female dog named Bico and Preta respectively.

TheTerceira Mastiff was saved from extinction by a few dedicated breeders who began to promotethe breedin the 21st century. Oneof thesebreederswas João Paulo Barbosa, who foundedthe kennel club "Cão da Serra de Aires"in 2006withthe goalof preservingthebreed. Thanks tothe efforts of Barbosaand otherbreeders,theTerceiranMastiff has madea comebackin recent yearsand is nowrecognizedas adistinctbreedbyseveralkennel clubs, includingthe Portuguese Kennel Clubandthe Federation Cynologique Internationale.

The Terceira Mastiff is classified as a working dog by most kennel clubs. The breed is used for hunting wild boar and other game animals on Terceira Island. The dogs are also used for guarding livestock and property against predators such as foxes and coyotes. In recent years, some Terceiran Mastiffs have been trained as service dogs for people with disabilities or special needs.
