The sequence follows FCI breed standard.
DATE OF PUBLICATION OF THE OFFICIAL VALID STANDARD
: October 2009
: A sturdy low-set dog rather long in proportion to height. Untrimmed, harsh coat with definite ruff around neck extending to breastbone, assists hard bitten and rugged appearance.
: Strong terrier character; alertness, activity and soundness. Essentially a working terrier, it is equally suited as a companion dog owing to its loyalty and even disposition.
BEHAVIOUR / TEMPERAMENT
: Friendly, extrovert, obedient and anxious to please. Lives happily in town or country. Not aggressive but courageous if attacked.
: Head long with flat skull of moderate width, full between eyes, with slight but definite stop. Muzzle strong but powerful, of equal length to that of skull, which should be covered with a soft, silky ‘top-knot’. Nose black, of moderate size, leather extending to bridge of muzzle.
: Jaws strong and punishing, scissor bite, i.e. upper teeth closely overlapping lower teeth and set square to the jaws.
: Relatively small with keen expression and of dark brown colour, set well apart and not prominent.
: Small, erect, pointed, well carried, set on moderately wide, free from long hair and sensitive in their use (puppies under six months excepted).
: Long, slightly arched, shapely and strong, blending into long, well laid shoulders.
: Long in proportion to height, strongly constructed, with well sprung ribs and chest of moderate depth and width. Level topline. Loins strong. Flanks deep.
: Previously customarily docked.
Docked: Set high and carried erect but not over back.
Undocked: Set high and carried upright as straight as possible, giving good overall balance.
: Forelegs well boned and perfectly straight, parallel when viewed from front. Pasterns strong without slope, slightly feathered to knee.
: Small, well padded, toes closely knit and moderately arched, turned neither in nor out, with strong black or dark toenails.
: Moderate length of quarters, broad with strong muscular thighs, stifles well turned and hocks well bent and let down. Viewed from behind, parallel, neither too wide nor too close.
GAIT / MOVEMENT
: Free, springy and forceful. When viewed from front, forelegs move truly without looseness of shoulder, elbows or pasterns. Hindquarters have drive and power, with free movement of stifles and hocks. Seen from rear, legs from hocks to ground parallel, neither too close nor too wide.
: Body coat consists of harsh straight dense top coat, approximately 6.35 cms (21/2 ins) long with short, soft-textured undercoat. Muzzle, lower legs and feet free from long hair.
: (a) Blue, steel blue or dark grey blue, with rich tan (not sandy) on face, ears, under body, lower legs and feet and around the vent (puppies excepted). The richer the colour and more clearly defined the better. ‘Top-knot’ blue or silver of a lighter shade than head colour.
(b) Clear sandy or red, smuttiness or dark shading undesirable. ‘Top-knot’ a lighter shade.
: Height: approximately 25.5 cms (10 ins) at withers. Weight: approximately 6.5kgs (14 lbs).
: 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.
Male animals should have two apparently normal testicles fully descended into the scrotum.
