- Completing hand stripping at least 3 times annually is mandatory to stop lower-layer dominance.
The Glen of Imaal Terrier is a tough but fun-loving dog, built for the rough terrain of the Irish valley that bears its name. Growing up in the hills of Wicklow County, south of Dublin, this dog was bred as a badger hunter, general farm dog, and companion. But unlike many other terriers, its instinct is to pursue the prey silently instead of alerting its owner with loud barks. It was first recognized by the American Kennel Club in 2004.
A broad head, short legs, and downturned ears characterize the Glen of Imaal. The water-resistant double coat consists of a rough outer layer and a soft lower layer with longer furnishings around the neck, ears, legs, and stomach. There are two main coat colors: blue brindle and a yellowish wheaten. Other coat colors (like blue and tan) are rarer and not favored by some breeders.

Common Health Issues
The Glen of Imaal is a fairly healthy breed with a life expectancy of 10 to 15 years. Some of its more common health problems include allergies, cataracts, progressive retinal atrophy, heart disease, cancer (the leading cause of death for older dogs), a loose kneecap that slips out of place, and hip and elbow dysplasia (a genetic developmental disorder that causes arthritis and lameness).
Another potential problem is Cushing’s disease, which causes the body to produce an excess of steroid hormones; common signs are increased appetite, sluggishness, hair loss, thin skin, and excess drinking and urination. A good breeder should ideally try to minimize or eliminate most genetic disorders, but there will always be health risks with any breed of dog.
Temperament
The Glen of Imaal has many of the personality traits of a typical terrier: it’s spirited, adventurous, brave, friendly, and hard-working, which should make it an excellent companion. This breed also has a very strong prey drive and may not be suitable in homes with other small animals. But unlike many terriers, the Glen of Imaal doesn’t have the constant, never-ending motor; it is less excitable and knows how to calm down. The breed still needs a lot of mental and physical stimulation, however, or else it might resort to some destructive and unwanted behavior such as chewing and barking.
How to Take Care of the Glen of Imaal Terrier
The Glen of Imaal is by no means an easy dog to care for. Its grooming, training, and exercise habits all require an engaged owner. But because of its more docile temperament, the breed might be a good choice for novice terrier owners who have little experience with this type. As with any other breed of dog, it is best to only work with high-quality breeders who adhere to strict health and maintenance standards. This should ensure the best possible start for your dog. Unfortunately, if you plan to adopt from a rescue shelter, it might be very difficult to find this dog in your area. There are very few rescue groups that specialize in the Glen of Imaal. Regardless, after it comes home, the dog will need a thorough physical examination at the vet and regular checkups after that.

The Best Dog Food
The Glen of Imaal will need about 1.5 cups of high-quality dog food per day. The exact amount will vary with the dog’s age, size, and activity level. This breed does have a tendency to gain weight, so you should not leave out food for it to eat after each meal.
Glen of Imaal Terriers commonly suffer from allergies, so it’s a relief that there are so many limited-ingredient and allergy-control dog foods available. Also, avoid feeding your dog anything containing legumes, as lentils and peas have been linked to heart failure in dogs, and this breed has a higher risk for heart disease.
Maintenance and Grooming
The Glen of Imaal requires weekly brushes to prevent matting. It also needs to be hand stripped two or three times per year. Hand stripping is a method of removing the top layer of the coat from the roots by hand. Owners practice this with wire coat terriers to maintain the consistency of the entire fur. Otherwise, if the top layer of fur is clipped, the soft lower layer of the coat might dominate. If you plan to groom this dog yourself, then it might be a good idea to invest in a grooming table. Otherwise, you should take the dog to a professional groomer who has experience with terriers. This will keep the dog looking great and also minimize any tendency for shedding. In addition to these regular grooming habits, owners should also check the ears weekly, brush the teeth once or twice a week, and trim the nails whenever they grow long.
Training
The Glen of Imaal is an intelligent, trainable breed with a strong drive and can-do spirit. But because of its independent mind and tendency to become bored easily, owners should break up training into smaller sessions, maybe five or 10 minutes long, or whenever its attention starts to wander. Keep the training varied and interesting to avoid repetition. This breed is capable of learning a wide variety of commands. In fact, it’s one of the few breeds that can learn to sit on its hind legs. This has earned the trick its own nickname: the Glen sit.
Exercise
The Glen of Imaal needs about 30 to 60 minutes of exercise per day. It enjoys long walks, runs, fetching, and playtime. Many owners may like the fact that this breed does not have endless reserves of energy. It should settle down and become docile after a bit of exercise. Nevertheless, this breed is well-suited for some athletic competitions. Earthdog trials are specialized for terriers and other vermin hunters because they simulate the way that the dog would naturally pursue its prey through underground dens.
Puppies
Glen of Imaal puppies are sensitive little dogs that need to be slowly introduced to physical activities. It takes about nine to 12 months to develop the full growth plates in their legs. Before then, your dog should be prevented from running, climbing, and exercising on hard surfaces. Early socialization and obedience training are important aspects of its psychological development. Puppy training classes are recommended but not necessary. If you have the time and patience, it’s possible to do it yourself.
Glen of Imaal Terriers and Children
The Glen of Imaal should be a friendly and fun companion for most kids, but there is always the possibility that young children may not tolerate and enjoy the dog’s high-energy motor and tendency to play roughly.
