How does the Bullmastiff differ from a Mastiff?
The Mastiff is an ancient British breed and its history can be traced back over 2,000 years. The Bullmastiff is a relative recent breed developed from crossing the Mastiff (60%) and Bulldog (40%) stock. The Bullmastiff’s shorter and squarer, more compact, more muscular look; shorter muzzle, higher energy level and generally more stubbornness are derived from the Bulldog part of the Bullmastiff’s ancestry. The most noticeable differences are temperament, the conformation of the body and heads and overall size of the dogs.
