The Bullmastiff was obtained by crossing 60% Mastiffs with 40%
Bulldogs in England. Mastiff Bulldog types can be found in records
as early back as 1795. In 1924 Bullmastiffs began to be judged.
Three generations of breeding of Bullmastiffs was required for Bullmastiffs
to be registered as purebreds. The Bullmastiff was used as a gamekeeper's
dog to track down, tackle and hold poachers. The dogs were fierce
and threatening, but were trained not to bite the intruders.
When the need for gamekeeper's dogs decreased the dark brindle
dogs so good for night camouflage gave way in popularity to the
lighter fawn coloration. It has been prized as a hunting guard,
as an aid in army and police work, and is used as a watchdog by
the Diamond Society of South Africa. Today's Bullmastiff is a reliable
family companion and guardian. It enjoys living with the family,
with whom it comforts itself well.
The Bullmastiff is massive, very powerfully built, but is not a
cumbersome dog. The large, broad skull is wrinkled and the muzzle
is broad, deep and usually darker in color. The forehead is flat
and the stop is moderate. The black nose is wide and has large nostrils.
The teeth meet in a level or undershot bite. The medium sized eyes
are dark hazel.
The V-shaped ears are set high and wide carried close to the cheeks
giving a square appearance to the skull. The strong tail is set
high, thicker at the root and tapering and is either straight or
curved, and reaches to the hocks. The back is short, straight and
level between the withers and the loin. The short, dense, slightly
rough coat comes in brindle, fawn, or red, often with black markings
on the head.
The Bullmastiff is a devoted, alert guard dog, with a good-natured
temperament. Docile and affectionate, but fearless if provoked.
Although unlikely to attack, it will catch an intruder, knock him
down and hold him. At the same time, it is tolerant of children.
Intelligent, even-tempered, calm and loyal, these dogs crave proper
training and leadership.The Bullmastiff is extremely powerful and
needs a pack leader who is confident and consistent with set boundaries.
They should be thoroughly educated and trained to listen to their
master and should be taught not to pull on the leash. When going
in and out gateways or doorways the dog should allow the humans
to enter and exit first out of pack respect, because in the dog's
mind, the leader goes first. The dog should be taught to walk to
heel. This is most important as not only do dogs have migration
instincts and need to walk daily, but instinct tells a dog the alpha
goes first. Be sure to socialize extensively with both people and
other dogs at an early age. They can be okay with other house hold
pets depending on how well the owners communicate with the dog.
The Bullmastiff is a more dominant breed than the Mastiff. He tends
to slobber, drool at the mouth and snore. Puppies may seem uncoordinated.
These dogs are very sensitive to the tone of your voice and need
someone to speak with an air of assertiveness, but not harshly.
It is not a difficult dog but does require a handler who can assert
his authority. The Bullmastiff should never be banished to a kennel.
Meek or passive owners will find it hard to control this dog. It
will appear wilful, possibly aggressive with other dogs and reserved
with strangers if owners do not take the time to introduce the dog
to other dogs and know how to properly communicate what is expected
in a meaningful manner.

bloat It is a good idea to feed them two or three small meals a
day instead of one large meal. Gains weight easily, do not over
Bullmastiffs will do okay in a flat if sufficiently exercised.
It is relatively inactive indoors. They can not tolerate extremes
Bullmastiffs need to be taken on at least two walks a day to fulfil
their primal canine instinct to migrate. Those individuals who do
not get this need met are more likely to develop problems. While
out on the walk the dog must be made to heel beside or behind the
person holding the lead, as in a dog's mind the leader leads the
way, and that leader needs to be the human. Teach them to enter
and exit all door and gateways after the human.
Under 10 years.
