Having a great coat for weather protection, the hair on the Bullmastiff is very short. With a distinct black mask around muzzle, the coat on this breed should be dense and somewhat coarse to the touch.

Overview
The Bullmastiff makes a great companion, and guard dog. Although intimidating at times, this breed can be very affectionate. Loving human attention, this breed is calm, gentle, and even-tempered.

Character
Being shy around strangers, this dog should be properly socialized during puppyhood. Used many times as an alert or guard dog, this breed should also be introduced to other animals at an early stage to avoid any altercations that may arise. The Bullmastiff is a powerful, yet at times docile breed.

Temperament
This willful dog requires a firm trainer to avoid any dominance issues. The Bullmastiff is fairly good-natured, sweet, and loveable, however this dog is not recommended for the average owner. His sheer size means he should not be placed in a home with small children as unintentionally, this breed can easily knock a child down.
