The Cesky Terrier was developed to be a well-muscled, short legged and well-pigmented hunting terrier that could be worked in packs. The Cesky Terrier has natural drop ears and a natural tail. The Cesky is longer than it is tall and has a topline that rises slightly higher over the loin and rump. It sports a soft, long, silky coat in shades of gray from charcoal to platinum. The correct coat is clipped to emphasize a slim impression. The hallmarks of the breed should be unique unto itself with a lean body and graceful movement.
Head is about 7 to 8 inches long, 3 to 4 inches wide and is shaped like a long, blunt wedge. The plane of the forehead forms a slight but definite stop with the bridge of the nose. The breadth between the ears is slightly larger for a dog than a bitch. The head should join the neck smoothly. Eyes - Almond shaped of medium size. Slightly deep set with a friendly expression. The color is brown or dark brown. Ears - Medium size, dropping in such a way to well cover the orifice. Ears are set rather high with forward edge lying close to the cheek. Shaped like a triangle, with the shorter side of the triangle at the fold of the ear.
