The History of This Hybrid

The Bullmastiff and Rottweiler hybrid has been around for years. Both the Bullmastiff and the Rottweiler are popular dogs that have been used for guarding purposes throughout history.

As guard dogs and property protection animals, both of these breeds have a keen sense of awareness.

To help you truly understand this mix, we will break down the breeds that make up the Rottie Bullmastiff.

Bullmastiff History and Origin

The Bullmastiff is a large working breed dog that originated in England in the mid-eighteen hundreds.

These dogs were used as estate guardian animals and were also relied on to ward off poachers. Bred by gamekeepers for their strength, size, speed, and formidable appearance, these dogs can be traced back to the original Bully breeds.

In 1924, the bullmastiff breed was deemed a purebred dog by the English Kennel Club. The genetic background of this canine consists of approximately 40% Bulldog and 60% Mastiff. In the year 1934, the American Kennel Club also began recognizing Bullmastiffs as purebred dogs.

The Origin of the Rottweiler

Although the precise origins of the Rottweiler breed are unknown, these dogs are believed to be descended from Roman drover cattle dogs.

In the Roman region of Rottweil, Germany, these dogs were used as guardians and land protection animals. They were also used for a range of herding applications and were even preferred by the Roman army.

Later, in the Middle Ages, Rottweilers would accompany butchers for protection when buying and trading.

Additionally, Rottweilers were used to pull carts and goods. The Rottweiler breed was first officially recognized by the American Kennel Club in the year 1931.

First of all, the Bullmastiff Rottweiler mix is a large breed of dog. Powerful and athletic, this hybrid is not for the faint of heart.

With the tendency to become stubborn, dominant, protective, or in some instances, aggressive, this is a mixed breed for experienced owners only. Additionally, this mix may be mellow or very active.

As such, you should be ready to dedicate plenty of time and energy to training and daily physical activity like walks.

Although this dog may be mellow and calm, the mix also has an equal chance of becoming highly active.

In fact, owning a large breed or giant breed can cost three times as much as owning a small breed dog.

Finally, this hybrid is not a purebred dog. As a mixed breed, it combines one Rottweiler and one Bullmastiff parent.

Certain traits like appearance, temperament, personality, and even size, can be unpredictable with this dog.

Therefore, unlike with purebred dogs, it can be hard to know exactly what to expect with a mix like this.

This can make it difficult to anticipate potential training and health-related issues that may arise in the future.
