The English Mastiff is a large breed of dog.
A very old breed, it was depicted in Egyptian monuments as early as 3000 BC and has had varied roles throughout history from dogs of war, bear-baiting to guardians of castles and large estates.
Despite their impressive size, Mastiffs are relatively placid and readily trained.
