The appearance is that of a dog of medium size, with a body that is square. Compactly built, muscular and powerful, for great endurance and speed. Elegant in appearance, of proud carriage, reflecting great nobility and temperament. Energetic, watchful, determined, alert, fearless, loyal and obedient.
Long and dry, resembling a blunt wedge in both frontal and profile views. When seen from the front, the head widens gradually toward the base of the ears in a practically unbroken line. Eyes almond shaped, moderately deep set, with vigorous, energetic expression. Iris, of uniform color, ranging from medium to darkest brown in black dogs; in reds, blues, and fawns the color of the iris blends with that of the markings, the darkest shade being preferable in every case. Ears normally cropped and carried erect. The upper attachment of the ear, when held erect, is on a level with the top of the skull. Nose solid black on black dogs, dark brown on red ones, dark gray on blue ones, dark tan on fawns. Lips lying close to jaws. Jaws full and powerful, well filled under the eyes.
Neck proudly carried, well muscled and dry. Well arched, with nape of neck widening gradually toward body. Length of neck proportioned to body and head. Withers pronounced and forming the highest point of the body. Back short, firm, of sufficient width, and muscular at the loins, extending in a straight line from withers to the slightly rounded croup. Chest broad with forechest well defined. Ribs well sprung from the spine, but flattened in lower end to permit elbow clearance. Brisket reaching deep to the elbow. Belly well tucked up, extending in a curved line from the brisket. Loins wide and muscled. Hips broad and in proportion to body, breadth of hips being approximately equal to breadth of body at rib cage and shoulders. Tail docked at approximately second joint, appears to be a continuation of the spine, and is carried only slightly above the horizontal when the dog is alert.
Shoulder Blade-sloping forward and downward at a 45-degree angle to the ground meets the upper arm at an angle of 90 degrees. Length of shoulder blade and upper arm are equal. Height from elbow to withers approximately equals height from ground to elbow. Legs seen from front and side, perfectly straight and parallel to each other from elbow to pastern; muscled and sinewy, with heavy bone. In normal pose and when gaiting, the elbows lie close to the brisket. Pasterns firm and almost perpendicular to the ground. Dewclaws may be removed. Feet well arched, compact, and catlike, turning neither in nor out.
Smooth-haired, short, hard, thick and close lying. Invisible gray undercoat on neck permissible.
The angulation of the hindquarters balances that of the forequarters. Hip bone falls away from spinal column at an angle of about 30 degrees, producing a slightly rounded, well filled-out croup. Upper shanks at right angles to the hip bones, are long, wide, and well muscled on both sides of thigh, with clearly defined stifles. Upper and lower shanks are of equal length. While the dog is at rest, hock to heel is perpendicular to the ground. Viewed from the rear, the legs are straight, parallel to each other, and wide enough apart to fit in with a properly built body. Dewclaws, if any, are generally removed. Cat feet as on front legs, turning neither in nor out.
