1. Key Characteristics of Bullmastiffs
Bullmastiffs are large, strong, powerful dogs. They are intelligent and protective.
Their short coat comes in colors of red, fawn and brindle.
2. Where Bullmastiffs Came From
Evidence of Bullmastiffs dates to the 1700s, but these dogs are mostly known for their work in England around 1860.
Poachers would target large estates and game preserves. A dog was enlisted to ward off the poachers and, if needed, attack on command.
The dogs would actually pin down the poacher and hold them without causing great harm until the gamekeeper could arrive. They could run short distances quickly and quietly.
The dog was created by crossing Bulldogs (40%) and Mastiffs (60%). Dark brindle colors were desired for night work, and the dogs with this coat color were referred to as night dogs.
The American Kennel Club (AKC) added Bullmastiffs to its breed registry in 1933.
3. How Friendly Are Bullmastiffs?
In addition to the drooling and snoring, Bullmastiffs are intelligent, loyal, protective dogs who are eager to please. They are active, confident, alert yet affectionate, and tolerate children well.
They don’t bark much and can live comfortably in apartments with daily exercise.
Bullmastiffs are fine with other pets as long as they are properly socialized. They require obedience training with a leader who is firm but not harsh. Know that Bullmastiffs don’t do well in kennels.
