High Quality Content by WIKIPEDIA articles! The Kerry Blue Terrier is a breed of dog. Mistakenly thought to be from County Kerry in South West Ireland, it`s actually from Tipperary in South Central Ireland. In Ireland it is often called the Irish Blue Terrier. Originally bred to control "vermin" including rats, rabbits, badgers, foxes, otters and hares, over time the Kerry became a general working dog used for a variety of jobs including herding cattle and sheep, and as a guard dog. Today the Kerry has spread around the world as a companion and working dog. Despite winning Crufts (the most important UK dog show) in 2000, it remains an unfashionable breed, still distinctly uncommon, but not as threatened as some of the other terrier breeds such as Skye Terrier, Sealyham Terrier, and Dandie Dinmont Terrier.
