The Bullmastiff is a strong and powerfully built animal that possesses great intelligence and a
willingness to please, making them ideal family companions and protectors. Although large, the
breed remains both agile and active and is successful in conformation, obedience, agility,
tracking, carting and therapy work. The Bullmastiff’s coat may be red, fawn or brindle.

The Bullmastiff’s known history in England begins around 1860, when they were developed to
keep large estates and game preserves free of poachers. Gameskeepers needed a dog that
could track quietly, cover short distances quickly and pin and hold poachers without mauling
them. The foundation breeding was 60% Mastiff and 40% Bulldog; breeders were hoping to
create a dog faster and more aggressive than the Mastiff, yet bigger than and not as ferocious
as the Bulldog.

The Bullmastiff is fearless and confident, yet remains docile and sweet-natured with his family.
They are natural guardians of the home, but do not bark much, as silence was a virtue when
guarding estates. Bullmastiffs are independent thinkers and may not respond to traditional
obedience training. The breed does not require much exercise or grooming, and can live happily
in a house or apartment.

Bullmastiff Breed Standard
                 Working Group

General Appearance
That of a symmetrical animal, showing great strength, endurance, and alertness; powerfully built but active. The foundation breeding
was 60% Mastiff and 40% Bulldog. The breed was developed in England by gamekeepers for protection against poachers.

Size, Proportion, Substance
Size-Dogs, 25 to 27 inches at the withers, and 110 to 130 pounds weight. Bitches, 24 to 26 inches at the withers, and 100 to 120
pounds weight. Other things being equal, the more substantial dog within these limits is favored. Proportion-The length from tip of
breastbone to rear of thigh exceeds the height from withers to ground only slightly, resulting in a nearly square appearance.

Expression-Keen, alert, and intelligent. Eyes Dark and of medium size. Ears-V-shaped and carried close to the cheeks, set on wide
and high, level with occiput and cheeks, giving a square appearance to the skull; darker in color than the body and medium in size.
Skull Large, with a fair amount of wrinkle when alert; broad, with cheeks well developed. Forehead flat. Stop-Moderate. Muzzle-Broad
and deep; its length, in comparison with that of the entire head, approximately as 1 is to 3. Lack of foreface with nostrils set on top of
muzzle is a reversion to the Bulldog and is very undesirable. A dark muzzle is preferable. Nose-Black, with nostrils large and broad.
Flews-Not too pendulous. Bite-Preferably level or slightly undershot. Canine teeth large and set wide apart.

Neck, Topline, Body
Neck-Slightly arched, of moderate length, very muscular, and almost equal in circumference to the skull. Topline-Straight and level
between withers and loin. Body-Compact. Chest wide and deep, with ribs well sprung and well set down between the forelegs. Back-
Short, giving the impression of a well balanced dog. Loin-Wide, muscular, and slightly arched, with fair depth of flank. Tail-Set on
high, strong at the root, and tapering to the hocks. It may be straight or curved, but never carried hound fashion.

Shoulders-muscular but not loaded, and slightly sloping. Forelegs-straight, well boned, and set well apart; elbows turned neither in
nor out. Pasterns straight, feet of medium size, with round toes well arched. Pads thick and tough, nails black.

Broad and muscular, with well developed second thigh denoting power, but not cumbersome. Moderate angulation at hocks.
Cowhocks and splay feet are serious faults.

Short and dense, giving good weather protection.

Red, fawn, or brindle. Except for a very small white spot on the chest, white marking is considered a fault.

Free, smooth, and powerful. When viewed from the side, reach and drive indicate maximum use of the dog's moderate angulation.
Back remains level and firm. Coming and going, the dog moves in a straight line. Feet tend to converge under the body, without
crossing over, as speed increases. There is no twisting in or out at the joints.

Fearless and confident yet docile. The dog combines the reliability, intelligence, and willingness to please required in a dependable
family companion and protector.``
