The Mastiff, often called the English Mastiff or OEM, is a beloved breed with a rich history.
The English Mastiff is one of the oldest and most ancient dog breeds, with depictions dating back to 2500 BC in Assyrian art. Mastiff-type dogs were used in ancient warfare, gladiatorial combat, and as guard dogs throughout European history. The breed came to England with Roman invaders and was later used for bear and bull baiting, guarding estates, and as war dogs. The modern English Mastiff was refined in the 19th century. After World War II, the breed was nearly extinct in England and was revived using dogs imported from the United States and Canada.
