Today, as a companion, the Bullmastiff still can be counted on for its watchdog abilities.
The Bullmastiff was developed in England in the 1800s to help gamekeepers keep poachers out of estates and game preserves. The dog needed to track quietly and pin and hold poachers without mauling them. The winning combination of size, speed, and ferociousness turned out to be 60 percent Mastiff and 40 percent Bulldog.
In theory, the Bullmastiff should be one of the world’s most popular guard dogs. Its endurance, strength and speed were developed so that it could overtake and capture intruders without mauling or killing them. Handsome and powerful, it has spread throughout all the continents of the world, but has never attained the popularity of its German equivalent, the Rottweiler. The reason for this is that the Bullmastiff can be a stubborn breed, resistant to obedience training, and overly protective of its human family.
