The Bullmastiff dog is a fearless and firm family protector. Although stand-offish towards other people, they are known to have a soft spot for their family.


Bullmastiffs are a large-sized working dog breed from England. Since the mid-1800s they were used as estate guardians to defend against poachers. Gamekeepers carefully bred them for power, speed, and size using a cross of the heavy, aggressive, tough Bulldog of the nineteenth century with the powerful, less aggressive Mastiff.

Care and Grooming

The Bullmastiffs need regular grooming and bathing. This attentive and intelligent dog might be bathed every week to once every 6 to 8 weeks, depending upon the level of activity and lifestyle.
