History of the Glen of Imaal Terrier

The exact origin of the Glen of Imaal terrier is unknown. But the breed hails from the mountainous and remote County Wicklow in Ireland. The farmers there needed hard-working dogs that could perform a variety of tasks. They used the terriers to exterminate vermin and to hunt badgers, foxes, and other game. 

One of the breed’s odd jobs gave it the nickname “turnspit dog.” People used their Glens to walk on a hamster wheel-like contraption that turned meat over a cooking fire. The dogs' powerful front legs served them well in this task.

The Glen of Imaal terrier began to gain recognition beyond its remote environment toward the end of the 1800s, and it slowly started arriving in North America in the early 1900s. But the American Kennel Club didn’t officially recognize the breed until 2004.

Glen of Imaal Terrier Care

Glen of Imaal terriers don’t require an excessive amount of exercise, though they still need activity every day. They also have some specialized grooming needs. And they should receive training and socialization from an early age.


Aim for at least an hour of exercise per day for your Glen of Imaal terrier. However, don’t allow your dog to engage in strenuous exercise until it is fully grown, as this can damage its growth plates. It’s even recommended to keep young Glens from jumping off furniture or going down steep stairs to prevent too much stress on their joints. Short walks and playing with toys are ideal ways to exercise your dog. Puzzle toys also can provide mental challenges. 

Moreover, keep your Glen of Imaal terrier on a leash or in a securely fenced area when outdoors. This breed has a strong prey drive and might take off chasing perceive prey if given the chance.


Brush your dog weekly to remove any loose fur and prevent tangles. Pay special attention to the fur around the ears, chest, stomach, and legs, which can be prone to matting. Also, this breed should have its coat hand-stripped a few times per year to remove the dead fur that doesn’t shed out on its own. 

Bathe your dog every month or so, depending on how dirty it gets. But check its ears at least weekly to see whether they need cleaning. Also, trim its nails roughly every month, and brush its teeth daily.


Begin training and socialization when your dog is a puppy to help prevent bad habits from forming. Glens are relatively smart, but they can be stubborn and get bored with repetitive training. So try to keep training sessions short, varied, and fun. Always use positive-reinforcement methods, such as treats and praise. 

Moreover, aim to expose your dog to different people and other dogs from a young age. This breed doesn’t always get along with other dogs, and it can be moderately reserved around strangers. But having lots of positive social experiences should help to curb these tendencies.
