About the Bullmastiff
The Bullmastiff was created in nineteenth-century England by gamekeepers who needed a dog fast enough to run down poachers and strong enough to hold them — a cross of Bulldog courage and Mastiff size. Modern Bullmastiffs are calm, quiet, and deeply loyal family guardians that need surprisingly modest exercise for their bulk. The trade-offs are a short seven-to-nine-year lifespan, heavy drooling, significant food and vet costs, and a protective instinct that demands early socialization. Suits experienced owners wanting a low-barking, devoted deterrent in a large package.
