Bullmastiff

Official U.K.C. Breed Standard.
Revised April 1, 1998

HISTORY -- In its present form, this is a fairly new breed, developed about 1860. The purpose for the development of the breed (a 60% Mastiff, 40% Bulldog cross), was to stop poaching in the English estates. The landowners wanted the poachers thrown and held but not mauled. The Mastiff, while powerful and courageous, was not fast enough and sufficiently aggressive. The Bulldog was a little too ferocious and not large enough for the task. This cross resulted in the development of a breed that was totally utilitarian.
The Bullmastiff was recognized by the United Kennel Club in 1948. GENERAL APPEARANCE -- The Bullmastiff is symmetrical in structure. The breed is powerfully built, showing great strength and endurance, and is active. It is alert and fearless, yet docile in manner. It may be red, fawn or brindle in color, with a natural tail and ears.

CHARACTERISTICS -- Fearless yet docile. Protective of property and children. They require a firm, loving owner; proper training is necessary to the development of good habits before adulthood is reached. Americans prefer a 60%-40% Mastiff-Bulldog cross in appearance, with the Mastiff characteristics predominating.

HEAD -- The head is broad, with well-developed cheeks and a fair amount of wrinkles when alert. The skull is large; the circumference of the skull may be equal to the height of the dog at the shoulder. The forehead is flat. The stop is moderate.
Severe Faults: Lack of foreface, with the nostrils set on top of the muzzle.

MUZZLE -- The muzzle is short, blunt and squared off. Its length is approximately 1 to 3 in comparison with that of the entire head. A dark muzzle is preferred.

NOSE -- The nose is black. The nostrils are large and broad.

EYES -- The eyes are dark and of medium size.

EARS -- The medium-sized, V-shaped ears are set wide and high on the skull, level with occiput and close to the cheeks, giving a squared-off appearance to the skull.

FOREQUARTERS -- The chest is wide and deep, with well-sprung ribs and a deep brisket. The shoulders are muscular, sloping, and powerful.
