The Irish Terrier is one of four terrier breeds developed in Ireland, and it may be the oldest. He was a dog of the common, used as an all-around farm dog and hunter.
Originally, there were black and tan and brindle, as well as red, Irish Terriers, but by the 20th Century, the breed was only red in color. The Irish Terrier was the first breed to be recognized by the English Kennel Club as a native Irish breed.
During the First World War, they were used as messenger dogs during trench warfare, proving their intelligence and usefulness. The Irish Terrier was recognized by the AKC in 1885 and a United States' breed club was started in 1896. Some of the Irish Terrier's talents include: hunting, tracking, retrieving, ratter, watchdog, guarding, police work and military work.
