Kerry Blue Terrier


Developed in Ireland, the Kerry Blue Terrier was an all-purpose farm dog — herding livestock, hunting vermin, and retrieving over land and water. It wasn’t until the 1920s that the breed became known outside of Ireland. Kerry Blues are born black, but the breed’s striking coat changes color with maturity. Though the breed has experience limited popularity as a pet, it has excelled as a police dog, as well as in herding and trailing.
