One of the many breeds of Irish Terrier, the Kerry Blue Terrier is a confident dog and looks as though it is sporting a beard. When first born, the Kerry Blue Terrier is black in colour, changing to blue within their first two year of life, hence their name Kerry Blue Terrier. They are taller and broader than their cousin, the Irish Terrier. This dog breed enjoys their exercise and their intelligence makes them reasonably easy to train.
