Bullmastiff

Last updated September 2016

A breed standard is the guideline which describes the ideal characteristics, temperament and appearance including the correct colour of a breed and ensures that the breed is fit for function. Absolute soundness is essential. Breeders and judges should at all times be careful to avoid obvious conditions or exaggerations which would be detrimental in any way to the health, welfare or soundness of this breed.

From time to time certain conditions or exaggerations may be considered to have the potential to affect dogs in some breeds adversely, and judges and breeders are requested to refer to the Breed Watch information related to this breed for details of any such current issues. If a feature or quality is desirable it should only be present in the right measure. However, if a dog possesses a feature, characteristic or colour described as highly undesirable, it must not be rewarded in the show ring.

Muzzle short; distance from tip of nose to stop approximately one-third of length from tip of nose to centre of occiput, broad under eyes and sustaining nearly same width to end of nose; blunt and cut off square, forming right angle with upper line of face, and at same time proportionate with skull. Under-jaw broad to end. Nose broad with widely spreading nostrils; flat, neither pointed nor turned up in profile. Flews not pendulous, never hanging below level of lower jaw.

Neck

Well arched, moderate length, very muscular and almost equal to skull in circumference.

Forequarters

Chest, wide and deep, well let down between forelegs, with deep brisket. Shoulders muscular, sloping and powerful, not overloaded. Forelegs powerful and straight, well boned, set wide apart, presenting a straight front. Pasterns straight and strong.

Body

Coat

Short and hard, weather resistant, lying flat to body. Long, silky or woolly coats highly undesirable.

Faults

Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog and on the dog’s ability to perform its traditional work.

Note

Male animals should have two apparently normal testicles fully descended into the scrotum.
