Bullmastiff Description

The Bullmastiff is a large dog that is powerfully built. It has a wide head that may have wrinkles, and the muzzle is short and square-shaped. The Bullmastiff will have large nostrils, and the nose should be black in color. The eyes will be moderate in size, and they should be dark hazel. The ears should have the shape of the letter “V,” and they should also be a dark color. They teeth will have an undershot bite, and the tail should be long enough to reach the hocks. Bullmastiffs have short coats that should be red, black or brindle in color.

The Bullmastiff was first bred in 1924 when the Mastiff was crossed with Bulldog. The Bullmastiff originates in England and was used to guard against poachers. While the dogs were trained to tackle the poachers, they were not bred to bite them. This dog has also been used in police work.


The Bullmastiff is a powerful guard dog that is loyal to those that care for it. It can sometimes be stubborn, but it is generally a docile breed unless it is threatened. Despite its size, the Bullmastiff is not as vicious as other guard dog breeds. If it is threatened by an intruder, it can use its weight to knock them over and then hold them.

While it is a large dog, it enjoys being around children and is an ideal breed for the family. Bullmastiffs must get the attention of those that own them. Because of their size, they should only be handled by someone who knows how to lead them.

Health Problems

Bullmastiffs may develop cancer. In addition to this, they may also develop tumors, eye problems, and hip dysplasia. Bloat is another common disorder that is seen with this breed. Owners will want to make sure they are not overfed. Bullmastiffs have a life expectancy which will generally be less than 10 years.


Because of its size, the Bullmastiff can become lazy. Owners will want to make sure they get medium levels of exercise. They can live in sizeable apartments if they are given exercise, though a small yard is recommended. The Bullmastiff does not function well in weather that is extreme.

Special Grooming Needs

The Bullmastiff has a short coat that is simple to maintain. A firm comb or brush should be used, and these dogs will not shed large amounts of fur. Owners will want to monitor the feet, to make sure they are not under stress due to the weight of the dog. The nails will also need to be trimmed.
