History of Kerry Blue Terriers
The blue terrier was developed in County Kerry, Ireland, and served as a multipurpose working dog for farmers and hunters. These dogs needed to hunt vermin, guard property, herd sheep and retrieve game from land and water — a true jack-of-all-trades.
While the exact origins of the breed are unknown, it is believed that Irish wolfhounds and soft-coated wheaten terriers may have contributed to the development of the blue terrier. By the early 20th century, the Kerry blue terrier had gained enough popularity to earn a spot in dog shows and was officially recognized by the American Kennel Club in 1922.
Today, Kerry blue terriers are celebrated both for their working skills and their joyful companionship.
