When talking about the best small dog breeds, the Glen of Imaal Terrier often flies under the radar. But for those who know and love them, this rugged little terrier is a true treasure. Bred in the remote Glen of Imaal in Ireland, this breed is brave, affectionate, and surprisingly calm for a terrier. If you’re on the hunt for a loyal companion that doesn’t bark unnecessarily, fits into the category of quiet small dog breeds, and adds personality to your home, this dog might just be your perfect match.
In this article, we explore everything about the Glen—from its history and traits to grooming, training, and whether it belongs in the miniature dog breeds, little dogs breed, or hypoallergenic small dogs categories.
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.

Glen of Imaal Terriers are little dogs breed in stature but pack a muscular build. Their bodies are longer than tall, giving them a unique, low-to-the-ground silhouette. They have strong forequarters, a big head, and a powerful jaw.

- Height: 12.5–14 inches
- Weight: 32–40 pounds
