The Story
The Irish Terrier is one of the oldest terrier breeds — possibly the ancestor from which all Irish terrier breeds descend. Known as the "Daredevil" of the terrier world, the Irish Terrier was described by its early breed standard as having "the fire of the Irish" — reckless courage combined with a passionate loyalty to its owner. In World War I, Irish Terriers served as messenger dogs and sentinel dogs on the Western Front, where their courage under fire was legendary. They are the only completely red-coated terrier breed and have been described as looking like a small Airedale.

Physical Profile

The Irish Terrier is a racy, lean, athletic medium-sized terrier with a long head, flat skull, and a strong wiry red coat that is dense and close-lying. The characteristically rich red colouring — from golden-red to deep red — with no white or other markings is a breed hallmark. The wiry coat forms a beard and eyebrows. The body is long-legged and athletic compared to most terriers.

Temperament & Personality
Irish Terriers are intensely loyal and courageous — their passion and fire is genuine. They are devoted to their family to a remarkable degree and are known for their almost dog-like responsiveness to their primary person. With other dogs they can be aggressive — their "reckless courage" trait means they will take on opponents much larger than themselves without hesitation. Their intelligence and trainability (when motivated) make them capable competitors.

Fun Facts
Irish Terriers served as messenger dogs in World War I, carrying messages through artillery barrages along the Western Front. Lieutenant-Colonel E. H. Richardson praised them as the bravest dog breed in the war.
The Irish Terrier was the fourth most registered breed in Britain in the 1880s — then one of the most popular breeds in the country before declining sharply in the 20th century.
The breed's nickname "Daredevil" and "Red Devil" reflect genuinely documented behaviour — Irish Terriers have been known to attack animals many times their size and sustain injuries without retreating.
