A Irish breed from the Glen of Imaal in Ireland, of old origin and initially bred as a working terrier. It was named after a small valley in the Wicklow mountains, south-eastern Ireland. The valley was named after the tribe Ui Mhail who lived there as early as year 737, but today the valley is empty. The breed has also been known under the name 'turnspit dog' as it was once kept not just as a hunter, but also ran in wheels to help heat houses. It was recognized in 1933 and to become a champion it had to pass an earthdog test known as 'teastas misneach'.

The body is rectangular in shape, with straight back and powerful chest. The legs are short and thick-boned. The tail is carried gaily. The coat is of medium length, wirey with soft undercoat.
