The general appearance is that of a strong compact, symmetrically built working dog, with the ability and willingness to carry out his allotted task however arduous. Its combination of substance, power, balance and hard muscular condition must convey the impression of great agility, strength and endurance. Any tendency to grossness or weediness is a serious fault.
The head is strong and must be in balance with other proportions of the dog and in keeping with its general conformation. The broad skull is slightly curved between the ears, flattening to a slight but definite stop. The cheeks muscular, neither coarse nor prominent with the underjaw strong, deep and well developed. The foreface is broad and well filled in under the eyes, tapering gradually to form a medium length, deep, powerful muzzle with the skull and muzzle on parallel planes. The lips are tight and clean. Nose black.
The length of the body from the point of the breast bone, in a straight line to the buttocks, is greater than the height at the withers, as 10 is to 9. The topline is level, back strong with ribs well sprung and carried well back not barrel ribbed. The chest is deep, muscular and moderately broad with the loins broad, strong and muscular and the flanks deep. The dog is strongly coupled.
The shoulders are strong, sloping, muscular and well angulated to the upper arm and should not be too closely set at the point of the withers. The forelegs have strong, round bone, extending to the feet and should be straight and parallel when viewed from the front, but the pasterns should show flexibility with a slight angle to the forearm when viewed from the side. Although the shoulders are muscular and the bone is strong, loaded shoulders and heavy fronts will hamper correct movement and limit working ability.
The coat is smooth, a double coat with a short dense undercoat. The outer-coat is close, each hair straight, hard, and lying flat, so that it is rain-resisting. Under the body, to behind the legs, the coat is longer and forms near the thigh a mild form of breeching. On the head (including the inside of the ears), to the front of the legs and feet, the hair is short. Along the neck it is longer and thicker. A coat either too long or too short is a fault. As an average, the hairs on the body should be from 2½ to 4 centimeters (approximately 1 to 1½ inches) in length.
Eyes - The eyes should be of oval shape and medium size, neither prominent nor sunken and must express alertness and intelligence. A warning or suspicious glint is characteristic when approached by strangers. Eye color, dark brown. Ears - The ears should be of moderate size, preferably small rather than large, broad at the base, muscular, pricked and moderately pointed neither spoon nor bat eared. The ears are set wide apart on the skull, inclining outwards, sensitive in their use and pricked when alert, the leather should be thick in texture and the inside of the ear fairly well furnished with hair. Mouth - The teeth, sound, strong and evenly spaced, gripping with a scissor-bite, the lower incisors close behind and just touching the upper. As the dog is required to move difficult cattle by heeling or biting, teeth which are sound and strong are very important.
The hindquarters are broad, strong and muscular. The croup is rather long and sloping, thighs long, broad and well developed, the stifles well turned and the hocks strong and well let down. When viewed from behind, the hind legs, from the hocks to the feet, are straight and placed parallel, neither close nor too wide apart.
