Bullmastiff is a keen athlete and security guard, clearly distinguishing between work and rest. As a true native of Foggy Albion, this charismatic robust man has his own independent opinion on any phenomenon, therefore, only a strong-willed and persistent owner can convince him of anything. However, to call the bullmastiff an incorrigible obstinate would be a clear exaggeration. The breed does not like to enter into confrontation with the owner, preferring pleasant partnership and mutual understanding to useless confrontation.
By this time, laws aimed at eradicating poaching were tightened in the UK, and natural areas were carefully protected. And since the English huntsmen could not cope with the lovers of unauthorized hunting alone, the need arose for strong, sturdy dogs capable of catching up and detaining the intruder until reinforcements arrived.
As a result: in every bullmastiff today there is a particle of the blood of a Bloodhound, St. Bernard, and even a Great Dane. And this despite the fact that the official progenitors of the breed continue to be the English Bulldog and Mastiff.
But in the 19th century, professionals like J. Briggs and W. Hollander were carried away by the "pumping" of the breed phenotype, which significantly increased the exterior and performance of animals. In particular, bullmastiffs became more impetuous in movement, without losing their natural viciousness and bulldog grip.
