KERRY BLUE TERRIER. Intelligent and game, the Kerry Blue Terrier is truly an all-purpose dog. Originally bred to hunt and retrieve, Kerries can be found today in the show, obedience, agility, herding and earthdog rings. A native of County Kerry, Ireland, the Kerry Blue Terrier was used as an all-round working and utility terrier, responsible for hunting small game and birds, retrieving from land and water, and herding sheep and cattle. It is thought that the peasantry of Ireland developed the Kerry as an answer to the nobility using Irish Wolfhounds. The Kerry was used to help the peasantry to silently hunt the noble hunting grounds.
