Spirited and game, full of confidence. An intelligent companion with strong sporting instincts.
Good tempered, having an affectionate nature, dignified, not shy or nervous. Mild in repose but full of courage when roused
Skull narrow, but deep and rounded; covered with profuse silky ‘top knot’ which should be nearly white. Jaw long and tapering. There must be no ‘stop’, the line from occiput to nose end straight and unbroken. Well filled up beneath eye, close fitting lips, without flew. Nostrils large and well defined.
Relatively small and bright. Ideal eye has appearance of being triangular. Blues have a dark eye; blue and tans have a lighter eye with amber lights, livers and sandies have a light hazel eye.
Moderately sized, filbert shaped, set on low, and hanging flat to cheek. Thin and velvety in texture; covered with short fine hair with fringe of whitish silky hair at tip.
Teeth large and strong. Scissor bite, i.e. upper teeth closely overlapping lower teeth and set square to the jaws.
Long and tapering, deep base with no tendency to throatiness. Springs well up from shoulders, and head carried rather high.
Forelegs straight, wider apart at chest than at feet. Pasterns long and slightly sloping without weakness. Shoulders flat and sloping.
Muscular and markedly flexible. Chest deep and fairly broad. Flat ribbed, deep through brisket which reaches to elbow. Back has natural arch over loin creating a definite tuck-up of underline. Body slightly greater in length than height.
Muscular and moderate length, arched loin with curved topline immediately above loins. Hindlegs have appearance of being longer than forelegs. Hocks strong and well let down, turning neither in nor out. Moderate turn of stifle.
Long hare feet with thick and well-closed-up pads. Pads sound and free from cracks or horny excrescences.
Moderate length, thick at root, tapering to a point and gracefully curved. Set on low, never carried over back.
Capable of galloping at high speed and have appearance of being able to do so. Action very distinctive, rather mincing, light and springy in slower paces and slight roll when in full stride.
Very distinctive. Thick and linty, standing well out from skin, but not wiry. A distinct tendency to twist, particularly on head and face.
Blue, liver, or sandy with or without tan. Darker pigment to be encouraged. Blues and blue and tans must have black noses; liver and sandies must have brown noses.
Height: about 41 cm (16 in) at withers. This allows for slight variation below in the case of a bitch and above in the case of a dog. Weight: 8-10 kgs (18-23 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.
