Watch this video for a quick overview of the Glen of Imaal Terrier — see the breed in action before diving into the details below.
The Glen of Imaal Terrier is one of Ireland's four native terrier breeds — and perhaps the least well-known of any terrier on either side of the Atlantic. Developed in the isolated Glen of Imaal valley in County Wicklow, Ireland, the breed's origins trace to the late 16th century when Queen Elizabeth I quartered foreign mercenary soldiers (primarily French and Hessian) in County Wicklow as payment for suppressing the Desmond Rebellions. These soldiers settled in the remote Wicklow glens and, over generations, bred sturdy working dogs suited to the harsh terrain — dogs capable of hunting badger, otter, and fox in rocky mountain dens, controlling vermin on small farms, and, notably, turning the large mechanical "turnspit" wheels used to rotate roasting meat over kitchen fires.
The Glen of Imaal is a distinctive-looking terrier: lower-slung than most, with slightly bowed front legs, a broad head, and a medium-length harsh wheaten or blue-brindle coat. They are stockier and heavier in bone than their low height suggests, built to work all day in the tightest underground burrows. Unlike most terriers, the Glen is notably quiet — they rarely bark unnecessarily, earning them the description "the strong silent type of the terrier world." AKC recognized in 2004, the Glen remains one of the rarest and least widely known terriers in North America, beloved by enthusiasts who prize their combination of genuine working ability, modest exercise needs, and unusual calm for a terrier.
