The wire fox terrier is a breed of dog, one of many terrier breeds. It is a fox terrier, and although it bears a resemblance to the smooth fox terrier, they are believed to have been developed separately.
The wire fox terrier is a sturdy, balanced dog weighing between 7 and 9.5 kg (15 and 21 lb). It should not be more than 15 1/2 in (39.37 cm) in height. Its rough, broken coat is distinctive. Coat color consists of a predominant white base with brown markings of the face and ears, and usually a black saddle or large splotch of color; there may be other black or brown markings on the body.
Two of the wire fox terrier's most distinctive traits are its energy and intelligence. It has a low threshold for boredom and requires stimulation, exercise and attention. The wire fox terrier is a companion animal that requires near-constant attention.
The dog should be alert, quick and ready to respond swiftly with enthusiasm. However, they should also be friendly, communicative, and playful if they receive the proper care and exercise. Bred to be independent thinkers, they are capable of tactical maneuvering for vermin and other sport.
Fox Terriers are two different breeds of the terrier dog type: the Smooth Fox Terrier and the Wire Fox Terrier. Both of these breeds originated in the 19th century from a handful of dogs who are descended from earlier varieties of British terriers, and are related to other modern white terrier breeds. In addition, a number of breeds have diverged from these two main types of fox terrier and have been recognised separately, including the Jack Russell Terrier, Miniature Fox Terrier and Rat Terrier. The Wire and Smooth Fox Terriers share similar characteristics, the main differences being in the coat and markings. They have been successful in conformation shows, more prominently in America than their homeland.
Small dogs were observed by the Romans in England in 54 BC being used by hunters to chase quarry into burrows and dens, demonstrating the instinctive terrier behaviour of "going to earth". English physician John Caius described the English terrier type in his 1577 work English Dogges. By the 18th century, it was recorded that all terriers were wire haired, and black and tan in colour.
The Toy Fox Terrier is a small terrier breed of dog, directly descended from the larger Fox Terrier but considered a separate breed.
Toy Fox Terriers are small dogs with a muscular and athletic appearance. Notable characteristic traits include a short glossy and predominantly white coat, coupled with a predominantly solid head, and a short, high-set tail. The breed has been deemed elegant and graceful with V-shaped ears and large eyes. The tail can be short and straight or long and shiny, and breeders often shorten the tail a few days after birth by clipping it about three-fifth of the way from the tip (at the third or fourth joint). The coat is short, fine, and glossy in black with tan, with areas of tan on the face; there are two other variants, one with 'chocolate' replacing the black in areas (the UKC does not allow this variant to be shown), and another which is all white and tan with no black at all. These variants are often known as 'Tri-Color', 'Chocolate', and 'Tan and White', respectively. The height ranges from 8.5–11.5 inches at the shoulder (21.5–29.2 cm) and weight from 3.5-9 pounds. They are in many ways similar to the Miniature Fox Terrier.
The Smooth Fox Terrier is a breed of dog, one of many terrier breeds. It was the first breed in the fox terrier family to be given official recognition by The Kennel Club (circa 1875; breed standard 1876). It is well known, and although not a widely popular breed today outside of hunting and show circles, it is extremely significant due to the large number of terriers believed descended from it.
The Smooth Fox Terrier's development as a breed is largely undocumented, but the dog has been known as a distinct breed in England since at least the 18th century; the first documented evidence of the Smooth Fox Terrier came in 1790, when a Colonel Thornton painted a portrait of his dog, Pitch.
The Smooth Fox Terrier entered the show ring during the mid-19th century, making it one of the earliest entrants in such events. The American Kennel Club recognized the Fox Terrier in 1885; one hundred years later, the Smooth Fox Terrier was recognized as being a distinct breed from the Wire Fox Terrier.
