More details about the Bullmastiff

Bullmastiff: Origins and history

The Bullmastiff is the result of a cross between the Mastiff and the Bulldog. The intention of first crossing of these two breeds was only to create fighting dogs, both powerful and flexible in nature. However, when official battles came to an end (in 1853), people realised that crossing these two breeds could create a new pure breed with good qualities. Forest rangers were particularly interested: they needed a flexible, powerful dog with a flair for fighting against poachers. Pure breed selection began in the 19th century and was perfected in the late 20th century by S. Moseley, who is considered the creator of the modern Bullmastiff.

FCI classification of the Bullmastiff

  • Group 2 - Pinscher and Schnauzer - Molossoid and Swiss Mountain and Cattledogs

  • Section 2 : Molossian type

Training a Bullmastiff

They are not the most docile dogs, but their desire to please their masters encourages them to be cooperative if the relationship is based on trust and mutual respect.

A lot of patience and consistency will be needed to get the best results with this dog who, in any case, will never be a perfectly obedient dog. They will always need a little time to think before obeying their master.

However, a clear advantage of this breed is their very good memory. In fact, everything they learn will stay with them for life.

Moreover, given their great size, it is advised to start training as soon as the Bullmastiff puppy arrives home. Life rules and educational bases must be established quickly to prevent any bad habits setting in early.

At first, call-back and walking on a lead without pulling will need to be acquired quickly in order to, on the one hand, keep control over this dog and, on the other hand, to ensure the walk is a pleasant experience.

The help of a professional obedience training and behaviour is desirable.
