Personality
General Temperament
Bullmastiffs are courageous protectors and gentle companions. They are cooperative and willing to please—to a point. Bullies have a stubborn side that should never be indulged or it will become tough to reverse. They are generally quiet and mild, but can be pushy and may become aggressive towards other dogs.
Family Life
Are Bullmastiffs Good with Kids? Bullmastiffs are protective, patient companions for children with whom they're raised, as long as they have been trained and socialized well from an early age.
(Note: Every dog has a unique personality and distinct life experiences that affect her disposition. As a rule, adults should always supervise playdates between kids and their four-legged friends.)
Are Bullmastiffs Good with Other Pets? Bullmastiffs don't make great housemates for other pets. Their prey drive is very high, which makes them dangerous for cats. They are also prone to aggression towards other dogs, especially males.
Protective
Bullmastiffs are highly protective of their turf, and especially of their families.
Are Bullmastiffs Good Guard Dogs? Originally bred to protect game from poachers in the English countryside, Bullmastiffs make excellent guard dogs. They are attentive to the perimeter of their property and will charge at anyone they feel poses a threat to their families. Their sheer size can intimidate intruders, and even some welcome visitors.
Energy Levels
These athletic animals do not have an excess of energy. They need daily exercise, but keeping them healthy does not require vigorous, lengthy activity.
Specific Concerns
- The Bullmastiff may be aggressive with other animals, particularly if she is not socialized early.
- She is prone to heat-related illnesses.
- She is stubborn and independent.
- She drools copiously, so furniture protectors will be key to a clean home.
