The Mastiff descended from the now extinct Pugnaces Britanniae. “Mastiff” comes from the Anglo-Saxon word “masty” meaning “powerful.” It is recognized as the oldest breed of English dog. It is believed to have been brought to Britain in the 6th century BC. They were used for the blood sports of bull, bear and lion baiting as well as dog fighting. There is evidence to say that the Mastiff was brought to the New World via the Mayflower, though actual documentation begins in the late 1800s. In 1835, the UK passed the Cruelty to Animals Act that prohibited the baiting of animals and the popularity of the Mastiff began to wane.

The Mastiff is a giant dog, with a muscular and powerful build. An alert and keen looking dog, they look menacing without even having to move. The coat of the Mastiff is close fitting, short, and sleek. They may have black markings around and/or between the eyes. Small ears fold down toward the sides of his head. An occasional brushing and wipe down with a damp cloth is all the grooming requirements your Mastiff needs. A Mastiff sheds constantly but lightly.
A dignified, courageous, and loyal dog, a Mastiff has a pleasant nature and a high level of intelligence. Due to his size, he makes an effective deterrent/watchdog. Despite their look, the Mastiff has a even temper and docile nature (unless they’ve been raised not to). Early socialization and confident, assertive training are required. A Mastiff is not a difficult dog to train. If you spend frequent time away from home, a Mastiff is not the dog for you; they thrive on companionship and affection. A Mastiff is not an overly active dog; he does best with a moderate amount of exercise. They don’t bark that much. Unfortunately, they are too large for apartment dwelling. They need a safe, secure yard in which to play and exercise. They should do great with children and animals (though they may try to dominate) that they’ve been raised with. If you’re doing a great job with him, your Mastiff should be friendly and welcoming to guests. If he isn’t, you’ve done something wrong.
