About the Bullmastiff Breed
The Bullmastiff is a powerful and active dog. It has an almost square proportion with a smooth gait. It is a very large dog, and was used as a guard dog of large estates. It has a high level of strength and endurance. All of these traits make it good at chasing down and overpowering intruders.
It is a very large, muscular dog, with short hair. The coat is red, fawn or brindle. Its ears fold down and frame a large head and a muzzle, which is usually black, or at least darker than the rest of it. The tail can look quite short compared to the body and naturally hangs downward between the back legs.
Near the end of the 19th century, poaching began to become a very big and dangerous problem for the guards of large estates. By breeding a Mastiff with a Bulldog, gamekeepers created a dog that kept silent, could attack when commanded, and subdue trespassers without injuring (too badly). The Bullmastiff tends to tackle the people it is sent after and then sit or lie on them, pinning them down. Despite this, the dog was bred to be able to work alongside people, which means it is amiable and affectionate, often known as a gentle giant.
However, the Bullmastiff is not a massively active dog, and so could even be content in a flat, assuming it is big enough for the dog to move its large bulk around. Overall, this breed doesn't require much grooming, but can drool a lot. It is prone to tumours and has a fairly short lifespan compared to other breeds of dog.
