Wire Fox Terrier.

AKC: alert, quick of movement, keen of expression, on the tip-toe of expectation; must stand like a cleverly made, short-backed hunter, covering a lot of ground; speed and endurance as well as power. UKC: a muscular but agile, active, small-to-medium hunting terrier with enough leg to run with the foxhounds in a hunt and built to go to ground after fox; although seldom used for hunting now, it keeps a strong prey drive and will dig tirelessly after underground vermin; the body is square. FCI 169: utilization 'terrier'; classed Group 3, Section 1 (large and medium sized terriers), working trial optional; always ready to deal with rats, rabbits and, of course, foxes. RKC: the ancestors of the Fox Terrier, the hunt terriers, contained broken-coated, wire-coated and smooth terriers; the Wire overtook the Smooth in popularity after 1900, but the demands of trimming have made the breed less popular. RKC terrier-group text: bred to pursue fox, badger, rat and otter above and below ground. No source read prints a chest-span test for this breed; the standards describe a deep, not broad chest and a short back. Wikipedia: developed in England by fox-hunting enthusiasts, descended from an extinct rough-coated black-and-tan working terrier of Wales, Derbyshire and Durham; bred to chase foxes into burrows, and the short strong docked tail was a handle to pull the dog back out..

The body

What the breed is built like. Registry standards give an ideal, not a range.

Height at the shoulder

UKC: double-coated, hard wiry outer coat over a soft dense undercoat; trimmed by stripping. FCI 169: dense very wiry, 2 to 4 cm, back and quarters harsher than the sides; leg hair dense and crisp. Color: white predominates with black, black and tan or tan markings; brindle, red, liver or slate-blue undesirable (FCI) or serious faults (UKC). AKC page: coat grooming 3, shedding 2.

The dog at home

What the breed asks of a day. The first thing most homes get wrong.

Exercise need

RKC (Fox Terrier, Wire): up to 1 hour per day. AKC page: energy level 4 of 5 and mental stimulation needs 4 of 5 (AKC bands, not mapped). UKC: retains a strong prey drive and will dig tirelessly after underground vermin. Wikipedia: a low threshold for boredom; needs stimulation, exercise and attention.

Energy

Breed clubAKC

AKC breed page trait score, 1 to 5: a breed-club tendency, never a measurement.

Grooming load

3 of 5 · RKC: grooming more than once a week; medium coat length; sheds. AKC page: coat grooming frequency 3 of 5, shedding 2 of 5 (AKC bands, not mapped). UKC: the coat is trimmed by stripping and blended into leg and face furnishings. Wikipedia: show dogs are hand stripped; many pets are clipped monthly by a groomer, which softens the coat.

Breed clubThe Royal Kennel Club

RKC is a UK registry band, not a study; mapped by the library rule (more than once a week = 3). Editorial and the UKC wording on stripping or monthly clipping would sit higher on the 1 to 5 scale; both stand.

The work

What it was built to do in the field, and what a test or trial asks of it.

Role

AKC: alert, quick of movement, keen of expression, on the tip-toe of expectation; must stand like a cleverly made, short-backed hunter, covering a lot of ground; speed and endurance as well as power. UKC: a muscular but agile, active, small-to-medium hunting terrier with enough leg to run with the foxhounds in a hunt and built to go to ground after fox; although seldom used for hunting now, it keeps a strong prey drive and will dig tirelessly after underground vermin; the body is square. FCI 169: utilization 'terrier'; classed Group 3, Section 1 (large and medium sized terriers), working trial optional; always ready to deal with rats, rabbits and, of course, foxes. RKC: the ancestors of the Fox Terrier, the hunt terriers, contained broken-coated, wire-coated and smooth terriers; the Wire overtook the Smooth in popularity after 1900, but the demands of trimming have made the breed less popular. RKC terrier-group text: bred to pursue fox, badger, rat and otter above and below ground. No source read prints a chest-span test for this breed; the standards describe a deep, not broad chest and a short back.

Breed clubAKC breed standard, 1991

AKC, UKC, FCI and RKC wording; Wikipedia is editorial.

Primary game

UKC: fox, built to go to ground after fox and bolt the quarry (history: hunters needed a dog that could go to ground and bolt the quarry, and bred a long-legged, mostly white terrier to run with foxhounds). FCI 169: rats, rabbits and, of course, foxes. AKC: fox, followed up a drain. RKC terrier-group text: fox, badger, rat and otter.

Breed clubUnited Kennel Club

Registry statements; the RKC badger and otter line is for the terrier group, not this breed alone.

Also used on

FCI 169: rats and rabbits in addition to fox. UKC: underground vermin, dug after tirelessly. RKC terrier-group text: badger and otter above and below ground. Wikipedia lists no further game.

Breed clubFCI-Standard N° 169, 2026

FCI and UKC wording; no source read ties the breed to badger or otter specifically.

Range

Runs with the hounds above ground: UKC says enough length of leg to run with the foxhounds in a hunt; AKC says speed and endurance, covering a lot of ground. Goes to ground singly. No source prints a range band.

Breed clubUnited Kennel Club

Editorial reading of UKC and AKC wording; no source prints a close, medium or big range.

Search pattern

UKC: built to go to ground after fox and bolt it; hunters wanted a terrier that could run with a pack of foxhounds, so these terriers ran with the hounds and went in when the fox went to ground; a strong prey drive and tireless digging after underground vermin. No source read for this breed states whether it bays or is silent at the quarry (AKC Earthdog general text: small terriers were bred to bark at the quarry in the den and to bolt or draw it).

Breed clubUnited Kennel Club

Breed-specific voice is not stated by AKC, UKC, FCI or RKC. The Earthdog sentence is about small terriers and Dachshunds as a group.

Field trial standard

AKC Earthdog eligible-breeds page lists Wire Fox Terrier. AKC Earthdog (non-competitive den tests for small terriers and Dachshunds): Introduction to Quarry (10 ft tunnel, one right angle, caged rats behind bars; handler may encourage), Junior Earthdog (30 ft den, three right angles, 30 s to reach the rats, 60 s working them, title after two passes under two judges), then Senior Earthdog (30 ft den, three right angles, false unscented exit and unscented bedding, 90 s work, recall from the den) and Master Earthdog (hunt to the den with a bracemate over 100 to 300 yd, mark the entrance, work the quarry through a 6 in narrowing). The AKC page says the tests were built for dogs bred to track game above and below ground, bark at the quarry in the den, and bolt or draw it for the hunter. FCI 169 classifies the breed Group 3, Section 1 (large and medium sized terriers), working trial optional.

How common the problems are

Evaluated dogs skew toward breeding stock; the numbers are still the best there are.

How to read this page

Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it. Editorial means expert opinion with no measurement behind it. Where two good sources disagree, both are shown and neither is averaged.

Published when the entry rests on the best information available from no fewer than three independent sources, checked by a second pass that did not write it. 7 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
