From the AKC Breed Information:
The Glen of Imaal Terrier is a rough-and-ready working terrier that is the least known of the four terrier breeds native to Ireland. Longer than tall and sporting a harsh coat of medium length, the Glen is very much a big dog on short legs. The Glen is the only terrier breed of Ireland not defined by a single color. Acceptable colors for the breed are various shades of wheaten, blue and brindle.
A Look Back:
Initially bred to rid the home and farm of vermin, and hunt badger and fox, these rugged dogs also had a unique task for which they were expressly designed to perform - they were turnspit dogs. The turnspit was a large wheel which, when paddled by the dog, would turn a spit over the hearth -- a canine propelled rotisserie. Today's Glens are very much the same as the Glens that worked the lowlands of County Wicklow 100 years ago, with very little refinement or influence by fashion.
