In its present form, this is a fairly new breed, developed about 1860. The purpose for the development of the breed (a 60% Mastiff, 40% Bulldog cross), was to stop poaching in the English estates. The landowners wanted the poachers thrown and held but not mauled. The Mastiff, while powerful and courageous, was not fast enough and sufficiently aggressive. The Bulldog was a little too ferocious and not large enough for the task. This cross resulted in the development of a breed that was totally utilitarian. The Bullmastiff was recognized by the United Kennel Club in 1948.
Bullmastiff is symmetrical in structure. The breed is powerfully built, showing great strength and endurance, and is active. It is alert and fearless, yet docile in manner. It may be red, fawn or brindle in color, with a natural tail and ears.
High spirited, alert and reliable, the Bullmastiff is a dependable family companion and protector.
