History The Bullmastiff was bred to aid gamekeepers in
protecting the game on large English estates. Poaching on the
estates was an expensive problem for the landowners, and it was the
gamekeeper's duty to catch the thieves. Gamekeepers needed a dog
that could track quietly, cover short distances quickly, and pin and
hold poachers without mauling them.
experimented with several breeds, looking to the mastiff, who was
too slow, and then the bulldog, who was at the time a more ferocious
dog than he is today. Out of these breeds, the bullmastiff was born.
He combined the best of both breeds for the job required of him. He
is now primarily a family companion with a calm, dependable
disposition when properly trained and socialized.
Behavior Active, agile, showing great endurance and of
solid build, the Bullmastiff has a symmetrical appearance. He is
earnest, courageous and alert, making him an excellent guard dog.
However, he is loyal and gentle, an excellent playmate for children.
The Bullmastiff has a very keen sense of smell and a dominant
personality. Early, firm, (though gentle) training is required.
Bullmastiffs are strong, powerful but sensitive dogs. For a
bullmastiff to become a well-behaved family member, consistency is
needed. Training and socialization is of high importance. Dogs of
this breed are natural guardians of their home and owners. No
special guard training is needed for a bullmastiff to react
appropriately if his family is endangered. Special approach to
bullmastiff training is needed, because these dogs do not like to
repeat the same actions again and again. Activities bullmastiffs can
really enjoy are obedience, agility, tracking, and carting.
Health Hip dysplasia, cancer, tumors, and gastric
torsion or bloat (twisted stomach). Other health concerns include
elbow dysplasia, eye problems, cardiac disease, hypothyroidism,
kidney problems, and panosteitis (bone disease).
Advice The Bullmastiff is not a good house dog. He
needs a lot of space and exercise. Regular brushing of the coat and
cleaning of his folds are required.
