History

The Mastiff, also known as the "English Mastiff", originated in England sometime before 55 BCE, around which time Julius Caesar made a note of how impressed he was with the Mastiffs the British were using to defend their legions during his attack. He brought some back to Rome to be used to hunt and fight animals and gladiators in arenas. Over time, Mastiffs found work as hunters, guardians, and war dogs. After WWII, there were only about 14 individuals left in Britain, bringing the breed to the brink of extinction. Luckily, Mastiffs were imported back from other countries to re-establish the breed. Modern Mastiffs are much more of a docile companion animal than early Mastiffs.
