Smooth Fox Terrier

The sequence follows FCI breed standard.


: Terrier


: When fox hunting became popular in England in the late 17th century, hunters found the need for a dog that could go to ground and bolt the quarry. Terriers, game and eager, were ideal for such a purpose but most of the early terriers were dark in color and too low on leg to run with a pack of foxhounds. Hunters began to develop a longer-legged terrier, predominantly white in color so as not to be mistaken for a fox. Early fox terriers were primarily smooth-coated. By the end of the 19th century, smooth and wire-coated Fox Terriers were in great demand, both as companions and show dogs. Although considered one breed for many years, interbreeding of Smooth Fox Terriers and Wire Fox Terriers ceased in the early 1900s. Except for coat, however, the two breeds are essentially identical. The Fox Terrier was recognized by United Kennel Club in 1912. The two breeds were separated effective January 1, 1999.


: The Smooth Fox Terrier is a muscular but agile, active, small-to-medium hunting terrier, with sufficient length of leg to run with the foxhounds in a hunt, and built to go to ground after fox. The body is square and covered with a short, dense, smooth coat. The head is moderately narrow, with a flat skull, a barely perceptible stop, and a powerful muzzle that is equal in length to the skull. Ears are set high and are V-shaped, dropping forward, and carried close to the skull. The tail is straight, set high, and normally docked, but not close to the body. The coat is predominantly white in color. The Smooth Fox Terrier is modeled on the symmetry and power of the Fox Hound. When standing, the distance between the front and rear feet is long in comparison to the relative shortness of the dog's back.


: The Smooth Fox Terrier is friendly, alert, active, and lively without being high-strung. Through his keen expression and alert bearing, ears up and tail quivering, the Smooth Fox Terrier gives the impression of a dog ready to go anywhere and take on any task. The Smooth Fox Terrier is bold but not aggressive with people. They are affectionate with children but may be too active for some. Although seldom used for hunting now, the Smooth Fox Terrier retains a strong prey drive and will dig tirelessly after any underground vermin.


: The head is long and moderately narrow. When viewed from the side, the skull and muzzle are equal in length, parallel to one another, and joined by a barely perceptible stop.




: The skull is flat and moderately narrow, tapering slightly toward the muzzle. Cheeks are flat and clean.




: The nose is black and fully pigmented. Disqualifications: Dudley nose; butterfly nose.


: The muzzle is strong and tapers slightly from stop to nose. Jaws are strong and muscular. There is a minimum of falling away under the eye, giving a moderately chiselled look. Lips are tight and darkly pigmented.


: The Smooth Fox Terrier has a complete set of comparatively large, evenly spaced, white teeth with a scissors bite.


: Eyes are deep set, moderately small, nearly round, dark in color, with a lively, intelligent, sometimes fiery expression. Eyerims are darkly pigmented.


: The Smooth Fox Terrier has small, V-shaped, button ears of moderate thickness. The ears are set high and the tips are carried close to the cheek. The topline of the folded ear is well above the level of the skull.


: The neck is clean, muscular, dry, and of moderate length. The neck gradually widens from the nape and blends smoothly into the shoulders.


: The Smooth Fox Terrier body is square, measured from point of shoulder to point of buttocks and from withers to the ground. The back is short and level, blending into a short, muscular, slightly arched loin. The chest is deep but not broad. The ribs extend well back, with the front ribs moderately arched and the back ribs well sprung and deep. The brisket extends to the elbow. The forechest is well filled but does not extend beyond the point of shoulder. The croup is nearly flat.


: The tail is set on high and customarily docked to a length that is proportionate to the body and provides a good handhold. The tail is straight and carried erect, but never curled or laying over the back.




: Shoulders are long, sloping, well laid back, fine at the point of shoulder, and well defined at the withers. The upper arm is shorter than the shoulder blade. The angle formed by the scapula and upper arm is approximately 90 degrees. The forelegs are strong, straight, and moderately well boned. The elbows are set close to the body but able to move freely in action. The pasterns are short, powerful, straight, and flexible. When viewed in profile, the pasterns are nearly erect.


: Feet are round, compact, and not too large. Toes are moderately arched. Pads are hard, tough, and well-cushioned. Dew claws may be removed.


: The hindquarters are strong and muscular. The thighs are long and powerful, stifles are well bent, and the hocks are well let down. When the dog is standing, the short, strong rear pasterns are perpendicular to the ground and, viewed from the rear, parallel to one another.


: A Smooth Fox Terrier moves with a brisk stride of moderate length. Coming and going, the forelegs and hind legs swing parallel to one another and perpendicular to the ground, like the pendulum of a clock. When moved on a loose lead at a moderate speed, the hocks and elbows are the same distance apart as the feet. Viewed from the side, the front legs extend well forward, but with very little height between foot and ground. The rear leg swinging forward contacts the ground at approximately mid-length of the body. As the leg moves beyond the rump, the foot is quickly lifted, creating a distinctive "snatch" of the hock. When moving, the back remains level.




: Coat is short, and close-lying but hard, dense, and abundant. Coat should cover the belly and the inside of the thighs.


: White is the predominant color.


: Desirable height for a mature male Smooth Fox Terrier should not exceed 15½ inches at the withers. A balanced dog of that height should have a back length from withers to root of tail of no more than 12 inches, and a head length of nor more than 7¼ inches or less than 7 inches. A balanced dog of these proportions should weigh about 18 pounds. Bitches are normally slightly lower in height and lighter in weight, but with the same proportions.
