General Appearance
Sturdy, compact , solid, small dog with good bone, short, smooth coat. No point exaggerated, balance essential.
Dogs showing respiratory distress highly undesirable.
 
Characteristics
Full of courage, yet with clown-like qualities. Bat ears and short tail characteristic features of the breed.
 
Temperament
Vivacious, deeply affectionate, intelligent.
 
Head and Skull
Head square in appearance and in proportion to dog’s size. Skull nearly flat between ears, domed forehead. The skin covering the skull and forehead should be supple enough to allow fine wrinkling when the dog is alert. Well defined muzzle, broad, deep and set back, muscles of cheeks well developed. Stop well defined. Lower jaw deep, square, broad, slightly undershot and turned up. Nose black and wide, relatively short, with open nostrils and line between well defined. Lips black, thick, meeting each other in centre, completely hiding teeth. Upper lip covers lower on each side with plenty of cushion, never so exaggerated as to hang too much below level of lower jaw.
 
Eyes
Preferably dark and matching. Moderate size, round, neither sunken nor prominent, showing no white when looking straight forward; set relatively wide apart and on same level as the stop.
 
Ears
’Bat ears‘, of medium size, wide at base, rounded at top; set high, carried upright and parallel, a sufficient width of skull preventing them being too close together; skin soft and fine, orifice as seen from the front, showing entirely.  The opening to the ear canal should be wide and open.
 
Mouth
Slightly undershot. Teeth sound and regular, but not visible when the mouth is closed. Tongue must not protrude.
 
Neck
Powerful, well arched and thick, of moderate length.
 
Forequarters
Legs set wide apart, straight boned, strong, muscular and short.
 
Body
Cobby, muscular and well rounded with deep wide brisket and ribs well sprung. Strong, gently roached back. Good ‘cut up’.  The body while broader at the shoulders should narrow slightly beyond the ribs to give definition to the relatively short, thick, strong, muscular loin.
 
Hindquarters
Legs strong, muscular and relatively longer than forelegs with moderate angulation. Absolute soundness essential. Hocks well let down.
 
Feet
Small, compact and placed in continuation of line of leg, with absolutely sound pasterns. Hind feet rather longer than the fore-feet. Toes compact; well knuckled; nails short, thick and preferably black.
 
Tail
Undocked, short, set low, thick at root, tapering quickly towards tip, preferably straight and long enough to cover anus, never curling over back nor carried gaily.
 
Gait/Movement
Free and flowing. Soundness of movement of the utmost importance.
 
Coat
Texture fine, smooth, lustrous, short and close.
 
Colour
Brindle, pied or fawn. Tan, mouse and grey/blue highly undesirable.
Brindle: a mixture of black and coloured hairs. May contain white provided brindle predominates.
Pied: white predominates over brindle. Whites are classified with pieds for show purposes; but their eyelashes and eye rims should be black. In pieds the white should be clear with definite brindle patches and no ticking or black spots.
Fawn: may contain brindle hairs but must have black eye lashes and eye rims.
 
Size
Ideal weight: dogs: 12.5 kgs (28 lbs); bitches: 11 kgs (24 lbs). Soundness not to be sacrificed to smallness.
 
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.
 
Note
Male animals should have two apparently normal testicles fully descended into the scrotum.
