Is the Bullmastiff right for you?

Species group:

The basics:
Around 1860, English gamekeepers developed the Bullmastiff from a mix of about 40% Bulldog and 60% Mastiff to protect large English estates from poachers. This working dog needed to be strong, fearless, and capable of attacking on command in the dark-- in other words, it needed to be loyal, trainable, and not overly aggressive once it had its prey.

This is not a dog that barks the alarm. In fact, it's a relatively quiet breed. This is a dog bred to apprehend the intruders. As a result, they can make splendid protection animals for owners who know how to manage them. For example, the Diamond Society of South Africa uses Bullmastiffs to protect their gems.

This powerful breed doesn't need to be taught to protect its people or its territory. It will do so automatically. What it demands is a responsible owner who can properly socialize the dog and make sure it doesn't represent a danger to others. If you don't know how to handle a somewhat independent dog that thinks for itself, you may find the Bullmastiff more of an insurance liability than a companion.

Appearance / health:
Large, muscular, and agile, Bull Mastiffs have characteristic large heads. The eyes are dark and of medium size. The V-shaped ears are carried close to the cheeks and set on high. The skull is large and broad and has some wrinkle when alert. The forehead is flat. The muzzle is broad and deep. The nose is black with large nostrils. The neck is extremely muscular.

The short coats of Bullmastiffs do not need much care, as they are said to be a "wash and wear" breed. Daily brushing is sufficient to remove dead hair. Teeth and ears must be cleaned regularly to prevent infections or dental problems.

They require moderate amounts of exercise. A short walk is sufficient to keep these dogs happy and healthy. These dogs must be always kept on a leash when outside the house.

The health issues common in Bullmastiffs include cancer, bloat, eye and thyroid problems, and allergies. In addition, hip and elbow dysplasia (a condition marked by poorly developed body parts) may occur in some dogs.

Behavior / temperament:
Bullmastiffs may exasperate their owners by their incessant biting and chewing. They make wonderful guard dogs owing to their protective territorial nature. Any intruder will find themselves knocked over by these large-sized dogs and pinned to the ground. Bullmastiffs are known to drool and snore. They have a high tolerance to pain.

They have a high learning rate. Several trainers may find it difficult to train independent-minded Bullmastiffs that do not enjoy doings the same tasks for a long time. Training needs to be firm, consistent, and capable of engaging them.

Bullmastiffs were bred to work silently, and hence rarely bark.
