The English Mastiff was founded in Britain. A very old breed, it was depicted in Egyptian monuments as early as 3000 BC. The breed fought alongside the British soldiers in 55 BC. Caesar brought a pack of Mastiffs to Rome where the dogs were put on display as an arena gladiator and forced to be in fights with human gladiators, lions, bull baiting, bear baiting and in dog to dog combat. They later became popular with the peasants in England where it was used as a bodyguard, protector of wolves and other dangerous predators and as a companion dog. In the eighteenth century the Mastiff was described: "As a lion is to a cat, so is a mastiff compared to a dog". Like most breeds by the end of World War ll the breed was almost extinct in England. Some of the Mastiff's talents include: watchdog, guarding, police work, military work, search & rescue, and weight pulling.



The Old English Mastiff is a massive dog. The Mastiff has a large, heavy square head with a well marked stop between the eyes. The muzzle should be half the length of the skull. The medium-sized brown to dark hazel eyes are set wide apart with a black mask around them. The nose is dark in color. The small ears are V-shaped and in proportion with the skull and are dark in color. The teeth should meet in a scissors bite but a slightly undershot bite is also acceptable in the show ring providing the teeth do not show when the mouth is closed. The tail is high-set with a wide base, tapering to a point reaching the hocks.
