The wire-haired fox terrier, like all other purebred dogs, are measured against breed standards of perfection. These standards are written descriptions of what each breed should look like. These written descriptions vary slightly in wording and content from one country to another, and from one registry to another.
This is a very brief summary of the standard appearance of the wire-haired fox terrier.
Males, up to 15 1/2 inches tall and weigh 16- 18 pounds; females proportionately shorter and about 16 pounds. Typical angular profile; long, rectangular head; button ears, and stiffly erect, docked tail. Harsh wiry coat, often wavy. Longer hair is usually left on eyebrows, muzzle, legs, and brisket. Permissible colors: White should predominate, usually with black and or tan on body; rarely all white. Markings often differ from smooth-fox terrier; for example, the wire may have a tan head with black body patches but such combinations are never observed in the smooth fox terrier.
