Who Bred the First Bullmastiff?

The first Bullmastiff was bred by gamekeepers in 19th century England to prevent poachers from stealing. The gamekeepers noted that the Mastiff and Bulldog had their limitations when it came to patrols. However, crossbreeding them resulted in the perfect gamekeeper’s companion.

English estate owners of the mid-19th century had a dilemma on their hands. Poaching had become rampant and was costing them some serious coin. To solve the problem, they hired gamekeepers to patrol the estates and catch any would-be thieves. 

For this job, gamekeepers needed a canine companion that could help them quietly track and tackle poachers to the ground without mauling them. Much to their frustration, known breeds of their time, the Mastiff and the Bulldog were not cut out for the job. 

The gamekeepers needed a dog that could cover short distances quickly. This was a problem for the native breeds used on English estates at the time as they weren’t suited to the task. 

The Mastiff wasn’t suitable because it was too slow and, therefore, ineffective when confronting thieves and poachers. The Bulldog satisfied the speed requirement; unfortunately, it was overqualified in the aggression department and would do more harm than good when catching poachers and their dogs. 

Bulldogs would also pick fights with the poachers, which would become very dangerous very quickly for a single gamekeeper, who would find himself up against a group of poachers. One gamekeeper couldn’t take on a bunch of thieves and their dog at once, even if the dog was a Bulldog. 

Gamekeepers were left stroking their chins, struggling to find a solution to the problem. They experimented with several breeds before circling back to the Mastiff and Bulldog. One of the gamekeepers had a lightbulb moment and proposed that the Mastiff and Bulldog be crossed.

Thus, the Bullmastiff was born

What Were Bullmastiffs Originally Used For?

With the perfect formula of 60% Mastiff and 40% Bulldog, the Bullmastiff was everything the gamekeepers hoped for and more. Poaching was punishable by death, so it was common for poachers to shoot it out with gamekeepers to escape the law. Bullmastiffs helped keep gamekeepers safe by pursuing poachers quietly, often catching them off guard. 

They could track poachers both quickly and quietly through forest undergrowth, even at night. And best of all, the Bullmastiff had the restraint to knock down poachers and pin them down until the gamekeepers caught up without taking a chunk off their faces or tearing into their jugulars.

Bullmastiffs had the restraint that Bulldogs did not, even with the poachers exerting every desperate effort to get away. They could keep the thieves pinned without hurting them, allowing the gamekeeper to take the poachers into custody. 

The Bullmastiffs quickly became indispensable to the profession of gamekeeping. They were perfect for the job by any metric. They were highly trainable and met all the temperamental requirements for a gamekeeper’s companion. They were physically built for their purpose, possessing speed, agility, and strength.

Being an athletic breed, it’s not hard to imagine the sight of a Bullmastiff charging at full speed, striking fear into the hearts of poachers wishing they had taken up a more honest occupation. 

Despite their mass and weight, Bullmastiffs were stealthy. They were trained not to bark or bite to avoid alerting other nearby poachers. The capacity for stealth was a big plus as it kept gamekeepers safe from large groups of poachers, and bought time for them to get help.

The breed quickly gained a reputation for being efficient trackers and catchers. In fact, their reputation was so far-reaching that John D. Rockefeller, a wealthy oil tycoon, imported the breed to the United States in the 1920s to guard his country estate. 

In 1933, they were officially recognized by the American Kennel Club

What Are Bullmastiffs Bred To Do?

While the answer to the question what were Bullmastiffs bred for? is that they were originally gamekeepers’ companions, today, the answer is very different. The age of gamekeepers and their bullmastiffs may be a thing of the past, but the breed continues to be loved and highly regarded today. 

The United Kennel Club (UKC) classifies the Bullmastiff as a guardian dog, while the American Kennel Club (AKC) classifies it as a working dog. However, unlike the 19th century, the Bullmastiffs of today are not exclusively bred to be working or guarding dogs. They are also bred as family pets.

Thanks to standardized breeding practices, the breed and its many fine traits have been preserved.

  • They are highly independent: Even though they make excellent pets, they can be challenging to train because they aren’t pushovers and aren’t as big on people-pleasing as other breeds. They are working dogs and don’t enjoy playing as much, especially when it’s hot outside. 
  • They need to be trained early: Early training and socialization are crucial while the dog is small enough to control. It is important to socialize them because they are naturally wary of strangers. The must be acclimatized to children and other pets at an early age to ensure that they don’t become aggressive when faced with kids or other dogs. 
  • They should have assertive owners: As mentioned, Bullmastiffs aren’t pushovers; they need owners who aren’t intimidated by their size and can be assertive during obedience training.
