Official Breed Standard
From the past history of the Staffordshire Bull Terrier, the modern dog draws his character of indomitable courage, high intelligence and tenacity. This coupled with his affection for his friends and children in particular; his off-duty quietness and trustworthy stability, makes him the foremost all-purpose dog.
The Staffordshire Bull Terrier is a smooth coated dog. He should be of great strength for his size and although muscular, should be active and agile.
Head and Skull:
Short, deep through, broad skull, very pronounced cheek muscles, distinct stop, short foreface, black nose.
Dark preferable but may bear some relation to coat colour. Round, of medium size and set to look straight ahead.
Rose or half-pricked and not large. Full drop or prick to be penalised.
The mouth should be level, i.e., the incisors of the bottom jaw should fit closely inside the incisors of the top jaw and the lips should be tight and clean. The badly undershot or overshot mouth to be heavily penalised.
Muscular, rather short, clean in outline and gradually widening towards the shoulders.
Legs straight and well-boned, set rather wide apart, without looseness at the shoulders and showing no weakness at the pasterns, from which point the feet turn out a little.
The body should be close-coupled, with a level topline, wide front, deep brisket, well-sprung ribs and rather light in the loins.
The hindquarters should be well-muscled, hocks let down with stifles well bent. Legs should be parallel when viewed from behind.
The feet should be well-padded, strong and of medium size.
The tail should be of medium length, low set, tapering to a point and carried rather low. It should not curl much and may be likened to an old-fashioned pump handle.
Free, powerful and agile with economy of effort. Legs moving parallel when viewed from front or rear. Discernable drive from hind legs.
Smooth, short and close to the skin.
Red, fawn, white, black or blue, or any of these colours with white. Any shade of brindle or any shade of brindle with white. Black and Tan or liver colour not to be encouraged.
Weight and Size:
Weight: Dogs 12.7 to 17.2 kg (28 to 38 lb). Bitches 11 to 15.4 kg (24 to 34 lb). Height (at shoulder), 35.5 to 40.6 cm (14 to 16 in), these heights being related to the weights.
To be penalised in accordance with the severity of the fault:
Light eyes or pink eye-rims.
Tail too long or badly curled.
Non-conformation to the limits of weight or height.
Full drop and prick ears.
Undershot or overshot mouths.
The following faults should debar a dog from winning any prize:-
Pink (Dudley) nose.
Badly undershot or overshot mouth. Badly undershot - where the lower jaw protrudes to such an extent that the incisors of the lower jaw do not touch those of the upper jaw. Badly overshot - where the upper jaw protrudes to such an extent that the incisors of the upper jaw do not touch those of the lower jaw.
Male animals should have two apparently normal testicles fully descended into the scrotum.
