📖 Breed History

The American Masti-Bull is a hybrid dog breed that is created by crossing an American Bulldog with a Mastiff, also known as the English Mastiff. Sometimes, this hybrid breed is referred to as the American Bandogge Mastiff, which can be a bit confusing. This term is used to describe hybrids that are a result of breeding any type of Bulldog with any type of Mastiff. The origins of this crossbreeding can be traced back to the 1960s when two breeders, John Swinford and Joe Lucero, started experimenting with creating the best guard dog. Swinford, an American veterinarian, and Lucero called their dogs American Bandog Mastiffs.

The American Bulldog is more closely related to the bull-baiting dogs of 17th century Great Britain rather than the English Bulldog. It is believed that the American Bulldog was brought to the United States during the colonial period and used for activities such as bull, bear, and buffalo baiting. In the southern states, farmers utilized them to catch feral pigs and cattle. The modern American Bulldog can trace its lineage back to these southern ancestors who thrived in Alabama and Georgia. Although the breed gained popularity in the 1980s as a guard and family dog, it is still not recognized by the American Kennel Club (AKC).

On the other hand, the Mastiff, also known as the English Mastiff, was initially bred as a guard dog. The exact origins of the Mastiff are unknown, but there is evidence of the breed dating back to 55 B. C. , as documented by Caesar after the Roman invasion of Britain. Even earlier accounts of Mastiffs have been discovered on ancient Egyptian monuments from 3000 B. C. The Mastiff breed was officially recognized by the AKC in 1885.
