Breed Origins & History
The Glen of Imaal Terrier hails from County Wicklow, Ireland. Developed for hunting vermin and badgers, these dogs had to be strong and low to the ground to chase down prey in burrows. Unlike the noisier terriers, Glens were bred to work in silence making them one of the more naturally quiet small dog breeds out there.
Though recognized by the American Kennel Club in 2004, the breed remains relatively rare outside of Ireland. This rarity contributes to their charm and makes them one of the more unique small dogs breed options today.
