Breed History:

The English Mastiff, commonly referred to as the Mastiff, is one of the oldest and most iconic dog breeds, with roots dating back thousands of years. Depictions of Mastiff-type dogs appear in ancient Babylonian, Egyptian, and Roman art, where they were used as war dogs, guardians, and hunting companions. The breed as we know it today was developed in England, where it was historically used to guard estates and castles, and even to face off against wolves and intruders.

In medieval times, Mastiffs were known for their courage and strength, often employed in bear baiting and other blood sports until these practices were outlawed. Following near extinction after World War II, the breed was revived through careful breeding efforts. Today, the English Mastiff is known for its imposing size, gentle temperament, and deep loyalty to its family.
