A Breed Standard is the guideline which describes the ideal characteristics, temperament and appearance of a breed and ensures that the breed is fit for function with soundness essential. Breeders and judges should at all times be mindful of features which could be detrimental in any way to the health, welfare or soundness of this breed.
GENERAL APPEARANCE: Well balanced, elegant and compact, sleek and cleanly built. Head and legs proportionate thus producing the correct balance.
BEHAVIOUR/TEMPERAMENT: Toy with Terrier characteristics. Alert, remembering that historically he could acquit himself satisfactorily in the rat pit. Never unduly nervous.
HEAD: Head long, narrow and well filled up under eyes.
CRANIAL REGION : Wedge-shaped.
Nose : Black.
Muzzle : Foreface tapers gently to provide wedge-shaped impression, in profile similar to that seen when viewed from front. Although an illusion of being overshot can result, any suggestion of snipey appearance is undesirable.
Lips : Compressed lips.
Cheeks : Without emphasis of cheek muscles.
Jaws/Teeth : Top and bottom jaws held tightly together. Jaws strong, with a perfect, regular and complete scissors bite, i.e. the upper teeth closely overlapping the lower teeth and set square to the jaws. Teeth level and strong.
Eyes: Dark to black, without light shading from iris. Relatively small, almond shaped, obliquely set and sparkling, not prominent.
Ears: Candle-flame shape, slightly pointed tips, placed high upon back of skull and proportionately close together. A guide to size can be obtained by bending ear forward -it should not reach eye. From nine months of age ear carriage must be erect. Entire inside of ear should face front. Leather of ear thin.
NECK: Long, graceful, slightly arched. Line of neck flowing into shoulders, and sloping off elegantly. Throatiness undesirable.
Back: Very slightly curving from behind shoulders to loin, falling again to root of tail.
Loin: Well rounded and well cut up.
Chest: Narrow and deep with ribs well sprung.
TAIL: Thick at root, tapering to point. Set low and not reaching below hock. 'Gay' tail undesirable if displayed to excess.
LIMBS: Fine bone eminently desirable.
Shoulders: Well laid back.
Elbows: Close to chest.
Forelegs: Falling straight from shoulders, providing a straight front.
Forefeet: Dainty, compact; split up between toes; well arched, with jet black nails, two middle toes of front feet rather longer than others
General Appearance: Buttocks gently rounded. A "tucked under" appearance undesirable.
Stifle: Well Angulated.
Hocks: Well let down; neither turning in nor out.
Hind feet: Cat-like, dainty; compact; split up between toes; well arched, with jet black nails, hare feet undesirable.
GAIT/MOVEMENT: Ideal fore-movement akin to the "extended trot"; hackney action not desirable; equally a "shuffling gait" undesirable. Hind action smooth with ease and precision combined with drive; there should be flowing quality to indicate true soundness.
COAT: Thick, close and glossy. A density of short hair required.
COLOUR: Black and tan. The black ebony, the tan likened to a new chestnut deeply rich. Colours not running or blending into each other, but meeting abruptly, forming clear and well defined lines of colour division. Forelegs tanned to knees in front. The tan then continuing inside and at back of forelegs to point just below elbows; thin black line up each toe (pencilling) and a clearly defined black mark (thumb mark) on centre of each pastern, and under chin. Hindlegs well tanned in front and inside with black bar dividing tan at centre of lower thigh. Heavy tan on outside of hindquarters (breaching or culottes) undesirable. Muzzle well tanned. The black continuing from nose along top of muzzle, curving below eyes to base of throat. A tan spot above each eye and a small tan spot on each cheek. Under jaw and throat tanned, lip line black. Hair inside ears tan (tan behind ears undesirable). Each side of chest has some tan. Vent and under root of tail, tan. White hairs forming a patch anywhere totally undesirable.
SIZE/WEIGHT: Ideal height 25-30 cm at the shoulder. Ideal weight 2.7-3.6 kg.
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.
- Aggressive or overly shy dogs.
- Any dog clearly showing physical or behavioural abnormalities shall be disqualified.
- Male animals should have two apparently normal testicles fully descended into the scrotum.
- Only functionally and clinically healthy dogs, with breed typical conformation, should be used for breeding.
