Bullmastiff

Bullmastiffs are smaller than Mastiffs but much more imposing than Bulldogs.

About the Bullmastiff

Bullmastiffs are powerfully built dogs, giving an impression of great strength without heaviness. These high-spirited, ever-alert, loyal dogs have a reputation for being tough, active and reliable protectors.

Despite their huge size, they are actually very friendly dogs who make excellent family companions.
