01/Overview
The Wire Fox Terrier is a small, athletic terrier known for its dense, wiry coat, keen expression, and confident personality. Developed to work alongside foxhounds and drive foxes from their underground dens, the breed remains energetic, alert, and full of determination.
Highlights
02/History
The Wire Fox Terrier originated in Great Britain, where terriers had long been used to control vermin and assist mounted hunts. Its primary purpose was to accompany foxhounds and bark to pinpoint the location of a fox when it had gone underground. Once the fox was forced back into the open, the hunt would continue.
Early fox terriers varied in coat, size, and appearance. Smooth-coated and wire-coated dogs were originally treated as varieties of the same breed and were sometimes interbred. Breeders gradually developed a more consistent type suited to the demands of foxhunting, including sufficient leg length to follow the hunt, a well-proportioned body, and a strong jaw.
The Wire Fox is believed to have developed from old British terrier stock, with possible contributions from rough-coated working terriers found in Wales, Derbyshire, and northern England. Its harsh coat provided protection from weather, brush, and rough terrain.
Organized breeding expanded during the nineteenth century as dog shows became increasingly popular. The Fox Terrier Club was established in England in 1876 and published an early Breed Standard that helped to define the desired structure, movement, and working character of both coat varieties.
The American Kennel Club recognized the Fox Terrier in 1885. Wire and Smooth Fox Terriers were initially registered as varieties of one breed, but the AKC officially recognized them as separate breeds in 1985. The American Fox Terrier Club, founded in 1885, serves as the AKC parent club for both breeds.
The Royal Kennel Club recognizes the Wire Fox Terrier in the Terrier Group. The Fédération Cynologique Internationale also recognizes it as a British breed and places it in Group 3, Terriers, Section 1, Large and Medium-Sized Terriers.
03/Appearance
An adult male Wire Fox Terrier stands approximately 15.5 inches tall at the withers and weighs about 18 pounds. A mature female is slightly smaller and typically weighs between 15 and 17 pounds.
Skull: The Wire Fox Terrier has a flat, moderately narrow skull that gradually decreases in width toward the eyes. The top line of the skull is nearly level, with little apparent stop.
Expression: The expression is keen, intelligent, and alert, reflecting the breed’s lively terrier character.
Eyes: The eyes are small, dark, moderately deep-set, and approximately circular in shape. They should convey a lively, attentive expression.
Ears: The ears are small, V-shaped, and fold forward, close to the cheeks. The fold is above the level of the skull, and the ear leather is of moderate thickness.
Muzzle: The muzzle is strong and gradually tapers toward the nose. The foreface is well filled beneath the eyes and should not appear weak, hollow, or excessively narrow.
Nose: The nose is black.
Bite: The Wire Fox Terrier has strong teeth that meet in a level bite, with the upper incisors slightly overlapping the lower incisors.
The Wire Fox Terrier is square in profile, with the length of the body from the point of the shoulder to the point of the buttocks approximately equal to the height at the withers. The back is short and level, contributing to the breed’s compact and balanced outline.
The chest is deep but not excessively broad, allowing the dog to perform its intended function. Bone is strong without appearing heavy or coarse, providing the strength, endurance, and agility expected of a working terrier.
Texture: The Wire Fox Terrier has a dense, harsh, and wiry outer coat with a short, soft undercoat. The coat lies close to the body and should be sufficiently hard to provide protection from inclement weather, difficult brush, and rough terrain. The hair on the jaws and legs is longer, creating the breed’s characteristic beard and furnishings.

Health
The Wire Fox Terrier is generally a healthy and hardy breed. A Wire Fox typically has a lifespan of 12 to 15 years. Preventive veterinary care, regular exercise, dental hygiene, balanced nutrition, and maintenance of a healthy weight can support any dog throughout its life.
The Wire Fox Terrier is lively, confident, curious, and highly alert. This energetic breed often approaches daily life with enthusiasm and can be entertaining, affectionate, and deeply devoted to its family.
Its strong terrier instincts may include digging, chasing, and investigating anything that moves. Early socialization and consistent boundaries are important, especially around unfamiliar dogs and small animals.
The Wire Fox Terrier can live successfully with children who understand how to interact respectfully with dogs. The breed’s energetic and sometimes boisterous nature may be better suited to families with older children.
Exercise Expectations
A healthy adult generally benefits from at least 60 minutes of activity each day, although particularly active individuals may need more. Games involving scent, problem-solving, retrieving, and controlled chasing can provide additional enrichment. Because of the breed’s strong hunting instincts, off-leash exercise should take place only in a securely enclosed area.
Grooming Expectations
The Wire Fox Terrier can adapt to apartment living when given enough exercise, training, and mental activity. Its tendency to bark and its high energy level may require additional management in homes with close neighbors.
A securely fenced yard can provide space for play, but fencing should be checked carefully because the breed may dig beneath barriers or pursue animals beyond the property. Outdoor time should not replace walks, training, and interaction with the family.
The Wire Fox Terrier usually does best in an active household that appreciates its confidence, humor, and independent spirit. Regular companionship and structured activity can help prevent boredom and destructive behavior.
05/Puppies
Wire Fox Terrier puppies are energetic, curious, and quick to investigate their surroundings. Early routines, positive socialization, patient training, and appropriate outlets for their natural terrier instincts help them develop into confident and manageable adults.
A Wire Fox Terrier puppy benefits from a predictable daily schedule that includes regular meals, potty breaks, sleep, play, training, and quiet time. A crate or secure puppy area can provide a safe place to rest and support housetraining when direct supervision is not possible.
Early socialization should introduce the puppy to different people, well-mannered dogs, household sounds, surfaces, vehicles, and unfamiliar environments. These experiences should remain positive and appropriate for the puppy’s age.
Training can begin as soon as the puppy arrives home. Short sessions can introduce name response, recall, leash walking, basic manners, and calm behavior around visitors. Because the breed may be easily distracted by movement or scent, recall and impulse-control exercises are especially valuable.
A Wire Fox puppy should receive a complete and balanced diet formulated for growth. Exercise should focus on supervised play, short walks, and gentle exploration rather than forced running or repetitive jumping while the puppy is still developing.
Regular veterinary visits are important during the first year. Grooming should also begin early so that the puppy becomes comfortable with brushing, nail trimming, ear checks, tooth brushing, and handling of the face, feet, and coat.

Official Standard of the Wire Fox Terrier
General Appearance: The Terrier should be alert, quick of movement, keen of expression, on the tip-toe of expectation at the slightest provocation. Character is imparted by the expression of the eyes and by the carriage of ears and tail. Bone and strength in a small compass are essential, but this must not be taken to mean that a Terrier should be "cloddy," or in any way coarse - speed and endurance being requisite as well as power. The Terrier must on no account be leggy, nor must he be too short on the leg. He should stand like a cleverly made, short-backed hunter, covering a lot of ground. N.B. Old scars or injuries, the result of work or accident, should not be allowed to prejudice a Terrier's chance in the show ring, unless they interfere with its movement or with its utility for work or stud.
Size, Proportion, Substance: According to present-day requirements, a full-sized, well balanced dog should not exceed 15½ inches at the withers - the bitch being proportionately lower - nor should the length of back from withers to root of tail exceed 12 inches, while to maintain the relative proportions, the head-as mentioned below-should not exceed 7¼ inches or be less than 7 inches. A dog with these measurements should scale 18 pounds in show condition - a bitch weighing some two pounds less - with a margin of one pound either way. The dog should be balanced and this may be defined as the correct proportions of a certain point or points, when considered in relation to a certain other point or points. It is the keystone of the Terrier's anatomy. The chief points for consideration are the relative proportions of skull and foreface; head and back; height at withers; and length of body from shoulder point to buttock -the ideal of proportion being reached when the last two measurements are the same. It should be added that, although the head measurements can be taken with absolute accuracy, the height at withers and length of back are approximate, and are inserted for the information of breeders and exhibitors rather than as a hard-and-fast rule.
Head The length of the head of a full-grown well developed dog of correct size - measured with calipers - from the back of the occipital bone to the nostrils-should be from 7 to 7¼ inches, the bitch's head being proportionately shorter. Any measurement in excess of this usually indicates an oversized or long-backed specimen, although occasionally - so rarely as to partake of the nature of a freak - a Terrier of correct size may boast a head 7½ inches in length. In a well balanced head there should be little apparent difference in length between skull and foreface. If, however, the foreface is noticeably shorter, it amounts to a fault, the head looking weak and "unfinished." On the other hand, when the eyes are set too high up in the skull and too near the ears, it also amounts to a fault, the head being said to have a "foreign appearance." Keen of expression. Eyes should be dark in color, moderately small, rather deep-set, not prominent, and full of fire, life, and intelligence; as nearly as possible circular in shape, and not too far apart. Anything approaching a yellow eye is most objectionable. Ears should be small and V-shaped and of moderate thickness, the flaps neatly folded over and dropping forward close to the cheeks. The topline of the folded ear should be well above the level of the skull. A pendulous ear, hanging dead by the side of the head like a Hound's, is uncharacteristic of the Terrier, while an ear which is semierect is still more undesirable. Disqualifications - Ears prick, tulip or rose. The topline of the skull should be almost flat, sloping slightly and gradually decreasing in width toward the eyes, and should not exceed 3½ inches in diameter at the widest part - measuring with the calipers - in the full-grown dog of correct size, the bitch's skull being proportionately narrower. If this measurement is exceeded, the skull is termed "coarse," while a full-grown dog with a much narrower skull is termed "bitchy" in head. Although the foreface should gradually taper from eye to muzzle and should dip slightly at its juncture with the forehead, it should not "dish" or fall away quickly below the eyes, where it should be full and well made up, but relieved from "wedginess" by a little delicate chiseling. While well developed jaw bones, armed with a set of strong, white teeth, impart that appearance of strength to the foreface which is so desirable, an excessive bony or muscular development of the jaws is both unnecessary and unsightly, as it is partly responsible for the full and rounded contour of the cheeks to which the term "cheeky" is applied. Nose should be black. Disqualifications - Nose white, cherry or spotted to a considerable extent with either of these colors. Mouth - Both upper and lower jaws should be strong and muscular, the teeth as nearly as possible level and capable of closing together like a vise the lower canines locking in front of the upper and the points of the upper incisors slightly overlapping the lower. Disqualifications - Much undershot, or much overshot.
Neck, Topline, Body: Neck should be clean, muscular, of fair length, free from throatiness and presenting a graceful curve when viewed from the side. The back should be short and level with no appearance of slackness – the loins muscular and very slightly arched. The term "slackness" is applied both to the portion of the back immediately behind the withers when it shows any tendency to dip, and also the flanks when there is too much space between the back ribs and hipbone. When there is little space between the ribs and hips, the dog is said to be "short in couplings," "short-coupled," or "well ribbed up." A Terrier can scarcely be too short in back, provided he has sufficient length of neck and liberty of movement. The bitch may be slightly longer in couplings than the dog. Chest deep and not broad, a too narrow chest being almost as undesirable as a very broad one. Excessive depth of chest and brisket is an impediment to a Terrier when going to ground. The brisket should be deep, the front ribs moderately arched, and the back ribs deep and well sprung. Tail should be set on rather high and carried gaily but not curled. It should be of good strength and substance and of fair length-a three-quarters dock is about right - since it affords the only safe grip when handling working Terriers. A very short tail is suitable neither for work nor show.
Forequarters: Shoulders when viewed from the front should slope steeply downwards from their juncture, with the neck towards the points, which should be fine. When viewed from the side they should be long, well laid back, and should slope obliquely backwards from points to withers, which should always be clean-cut. A shoulder well laid back gives the long forehand which, in combination with a short back, is so desirable in Terrier or Hunter. The elbows should hang perpendicular to the body, working free of the sides, carried straight through in traveling. Viewed from any direction the legs should be straight, the bone of the forelegs strong right down to the feet. Feet should be round, compact, and not large - the pads tough and well cushioned, and the toes moderately arched and turned neither in nor out. A Terrier with good-shaped forelegs and feet will wear his nails down short by contact with the road surface, the weight of the body being evenly distributed between the toe pads and the heels.
Hindquarters: Should be strong and muscular, quite free from droop or crouch; the thighs long and powerful; the stifles well curved and turned neither in nor out; the hock joints well bent and near the ground; the hocks perfectly upright and parallel with each other when viewed from behind. The worst possible form of hindquarters consists of a short second thigh and a straight stifle, a combination which causes the hind legs to act as props rather than instruments of propulsion. The hind legs should be carried straight through in traveling. Feet as in front.
Coat: The best coats appear to be broken, the hairs having a tendency to twist, and are of dense, wiry texture - like coconut matting - the hairs growing so closely and strongly together that, when parted with the fingers, the skin cannot be seen. At the base of these stiff hairs is a shorter growth of finer and softer hair - termed the undercoat. The coat on the sides is never quite so hard as that on the back and quarters. Some of the hardest coats are "crinkly" or slightly waved, but a curly coat is very objectionable. The hair on the upper and lower jaws should be crisp and only sufficiently long to impart an appearance of strength to the foreface. The hair on the forelegs should also be dense and crisp. The coat should average in length from ¾ to one inch on shoulders and neck, lengthening to 1½ inches on withers, back, ribs, and quarters. These measurements are given rather as a guide to exhibitors than as an infallible rule, since the length of coat depends on the climate, seasons, and individual animal. The judge must form his own opinion as to what constitutes a "sufficient" coat on the day.
Color: White should predominate; brindle, red, liver or slaty blue are objectionable. Otherwise, color is of little or no importance.
Gait: The movement or action is the crucial test of conformation. The Terrier's legs should be carried straight forward while traveling, the forelegs hanging perpendicular and swinging parallel to the sides, like the pendulum of a clock. The principal propulsive power is furnished by the hind legs, perfection of action being found in the Terrier possessing long thighs and muscular second thighs well bent at the stifles, which admit of a strong forward thrust or "snatch" of the hocks. When approaching, the forelegs should form a continuation of the straight of the front, the feet being the same distance apart as the elbows. When stationary it is often difficult to determine whether a dog is slightly out at shoulder but, directly he moves, the defect - if it exists - becomes more apparent, the forefeet having a tendency to cross, "weave," or "dish." When, on the contrary, the dog is tied at the shoulder, the tendency of the feet is to move wider apart, with a sort of paddling action. When the hocks are turned in-cow-hocks-the stifles and feet are turned outwards, resulting in a serious loss of propulsive power. When the hocks are turned outwards the tendency of the hind feet is to cross, resulting in an ungainly waddle.
Temperament: The Terrier should be alert, quick of movement, keen of expression, on the tip-toe of expectation at the slightest provocation.
Disqualifications: Ears prick, tulip or rose. Nose white, cherry or spotted to a considerable extent with either of these colors. Mouth much undershot, or much overshot.

Dog Sports
Fox Terriers are active, intelligent dogs with a rich history in hunting, therapy, and various canine competitions.
The tail is set high and carried upright, but it should not curl over the back. Traditionally docked in countries where the practice is permitted, the tail is strong and of sufficient length to contribute to the breed’s balanced outline and confident appearance.
A Note About Color: White should be the predominant color; brindle, red, liver, or slaty blue markings are objectionable. Otherwise, color is of little or no importance.

A Wire Fox Terrier should receive a complete and balanced diet suited to the dog’s age, activity level, and body condition. Portions should be measured because excess weight can place unnecessary strain on the joints and reduce the breed’s natural agility.
Puppies generally need three or four small meals each day before gradually moving to two meals. Most adults are fed twice daily, with the amount adjusted according to the food’s caloric density and the dog’s level of activity.
Treats should remain limited and may be used as part of training. Fresh water should always be available.
The Wire Fox Terrier is intelligent and capable of learning quickly, but it can also be independent and easily distracted. Training is most effective when sessions are short, varied, and supported by praise, food rewards, toys, or play.
Early socialization should expose the puppy to different people, dogs, environments, sounds, and surfaces. Recall training is especially important because the breed’s prey drive may encourage it to chase wildlife or other small animals.
Clear and consistent rules help prevent unwanted habits such as digging, excessive barking, or guarding valued objects. Harsh methods can create resistance, while patient and engaging training usually produces better results.
Dogs kept in a traditional show coat are hand-stripped to remove dead outer hair while preserving the coat’s harsh texture and rich color. Pet coats are sometimes clipped for convenience, although clipping may soften the texture and cause the colors to appear less distinct. Bathing is needed only occasionally unless the dog becomes dirty. Nails should be trimmed regularly, ears should be checked for irritation or debris, and teeth should be brushed routinely.
