The history of the Bullmastiff begins about the year 1860 in England. It is probable that the story of the breed is really centuries old, but proof is difficult. This type finally became sufficiently distinct for the English Kennel Club to grant recognition of the Bullmastiff as a pure-bred dog in 1924.

This dog is docile but fearless. He is alert and displays great endurance. The foundation breeding was 60% Mastiff and 40% bulldog.

Height and weight- males, 25-27 inches, from 110-130 pounds; females, 24-26 inches, and 100-120 pounds.
