History
Developed in 19th-century England by gamekeepers who needed a dog to catch poachers. Created by crossing the English Mastiff with the Bulldog to produce a dog that was fast, powerful and brave enough to pin a man without mauling. Known as the ‘Gamekeeper’s Night Dog.’
Temperament & Personality
Known for being loyal, protective, calm, courageous, devoted and gentle, the Bullmastiff brings a distinctive personality to any Australian household. This breed is typically excellent with children of all ages. Patient and gentle, they make wonderful family companions. As with all breeds, supervision during interactions with very young children is recommended. When properly socialised from puppyhood, this breed develops into a well-rounded companion that is loyal at home and protective in public. Their natural calm nature means they thrive in environments where they receive consistent attention and clear boundaries.
Training & Socialisation
Training a Bullmastiff requires understanding that this breed is eager to please and generally straightforward to train. Positive reinforcement methods work best—reward good behaviour with treats, praise and play sessions. Start socialisation early by introducing your Bullmastiff puppy to different environments, people and other animals. Australian puppy schools are an excellent starting point and are available in most suburbs and regional towns. Local councils across Australia often have specific requirements for dog behaviour in public, making basic obedience training not just beneficial but often necessary. Patience and consistency will yield the best results with this breed.
Care & Health
Regular hip and elbow screening essential. Bloat prevention through proper feeding practices. Moderate drooling. Not suited to extreme heat.
Living Conditions
A home with a securely fenced yard is ideal for the Bullmastiff. While they can adapt to larger apartments, regular outdoor access is important. In Australia’s varied climate, be mindful of heat—provide shade, fresh water and avoid exercising during the hottest parts of the day, particularly in summer.
