The Bullmastiff is a powerful dog, which was originally a cross between the English Mastiff and the English Bulldog. Bullmastiffs are described as fawn, red, or brindle. These are the only acceptable colors in the AKC standard. The fawn can range from a very light brown to a reddish brown. Red can range from a light red-fawn to a dark rich red.

Temperament: A Bullmastiff should be confident, yet docile. A Bullmastiff is courageous, extremely loyal to its family, calm, and loving. Bullmastiffs become intensely attached to their families. Bullmastiffs can also get along with other dogs, but it is common for males not to get along with other males, particularly if they are intact. The Bullmastiff can get along extremely well with children provided the dog has been properly trained and socialized. Parental supervision must be maintained when they are with children; as with most large dogs, they may knock smaller children down accidentally. A Bullmastiff, because of its history, is a very independent dog, and likes to make its own decisions. However, with good training, a Bullmastiff will look to its owner for "permission" to act on its instincts. Early socialization and obedience training with all members of the family will teach the dog to look to them before taking action. They are very athletic and muscular, making them incredibly fast and agile. They were never bred for hunting purposes, and should not show signs of aggression.

The lifespan for a Bullmastiff is generally from eight to 11 years. A Bullmastiff will not stop growing until it is about two and a half years of age.
