The history of the Bullmastiff begins in England around 1860. At that time, the owners of the fields and the forests had difficulties in controlling the ravages produced by poachers. Hunting owners needed a dog that would be able to immobilize any person who would dare to violate their property until the arrival of aid.

Thus, it was decided that the best combination would be that obtained by crossing the old English mastiff, giving the new breeds the courage and strength, and the English bulldog, for resistance. After several generations, the final combination (60% mastiff and 40% bulldog) resulted in the creation of a fearless dog that attacks, but does not mistreat, the command. Until recently it was a guard and protection dog, being usually named “The forest dog of the night”.

In 1924, the breed was stabilized, being officially recognized by the English Kennel Club. The American Kennel Club only recognized the breed in 1933. The breed became popular in military and police services, but today it is more often used for guard and protection dogs as well as pet dogs.
