A short-legged, sturdy Irish working terrier from County Wicklow. Brave and game at work yet notably calm and gentle at home, and quieter than most terriers.
Glen of Imaal Terrier scorecard
Overview
The Glen of Imaal Terrier is a sturdy, short-legged Irish working terrier standing around 32–36 cm at the shoulder and weighing roughly 14–16 kg — surprisingly heavy and powerfully built for its modest height. With its harsh medium-length coat, bowed front legs and substantial bone, it is a no-nonsense terrier developed in the rugged Glen of Imaal in County Wicklow, Ireland.
What sets the Glen apart from many terriers is its temperament: it is notably calmer and quieter at home than its lively reputation might suggest, brave and game at work yet gentle and affectionate with its family. It is recognised by The Kennel Club, which lists it among the vulnerable native breeds, making it one of Britain and Ireland's rarer terriers.
Good to know — a Glen of Imaal Terrier is best with a garden and manageable for committed beginners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The Glen of Imaal Terrier takes its name from the remote glen in the Wicklow Mountains where it was developed as an all-purpose working farm dog — used to control vermin, work to ground after badger and fox, and reportedly to turn the spit and perform other tasks around small holdings. It is one of four native Irish terrier breeds.
The breed was recognised by the Irish Kennel Club in the 1930s and is recognised by the FCI and The Kennel Club, which places it in the Terrier group. It remains scarce and appears on The Kennel Club's list of Vulnerable Native Breeds, reflecting its low annual registration numbers.
Temperament & family fit
Glens are known for being calmer, steadier and less excitable than most terriers, combining genuine terrier courage with a gentle, affectionate home temperament. They tend to be devoted, sturdy family companions, often good with children, and are typically quieter and less prone to constant barking than many of their relatives.
That said, the breed retains a strong prey drive and the independent, determined streak of a working terrier. Glens can be stubborn and may not always be reliable with small animals or unfamiliar dogs, so early socialisation and sensible management are important to bring out their best, mellow side.
- Families with children of all ages
- Owners ready for consistent training
- Homes with a secure garden
Training & intelligence
The Glen of Imaal Terrier is intelligent and capable but, like most terriers, can be strong-willed and independent, so training benefits from patience, consistency and reward-based methods that keep it motivated. Short, varied sessions suit it better than repetitive drilling.
Early socialisation helps temper its prey drive and any tendency to be wary of strange dogs, and recall should be trained carefully given the terrier instinct to chase. Owners who approach training with humour and consistency generally find the Glen a rewarding, willing partner within its terrier nature.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Keep sessions short, calm and consistent
Exercise needs
A healthy adult Glen of Imaal Terrier typically needs around an hour a day (roughly 60–80 minutes), split across walks, play and a little training. A good sniffy walk, some play and a little training usually keeps them content. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
The harsh, medium-length double coat needs regular brushing and benefits from periodic hand-stripping to maintain its proper texture rather than clipping, which softens the coat. Routine attention keeps it tidy and weatherproof. As with any dog, regular nail trimming, ear checks and dental care round out the grooming routine.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding considerations
Feed a complete, balanced diet suited to a sturdy small-to-medium dog, with portions controlled to maintain a healthy weight, as the Glen's heavy build and moderate activity mean it can gain weight if overfed. Keeping it lean reduces strain on its short-legged frame and joints; take veterinary advice on quantities.

The Glen of Imaal Terrier is generally a hardy, robust breed, but as a numerically small population it has a couple of well-recognised inherited conditions that responsible breeders screen for. Prospective owners should seek breeders who DNA-test and can show relevant results.
The best-known breed concern is an inherited eye disease, for which a DNA test is available, and the breed's short-legged (chondrodysplastic) build means joint and orthopaedic issues are also worth attention. Because the breed is rare, maintaining genetic and overall health is a priority for conscientious breeders, so choosing a health-testing breeder is especially important.
Common health conditions to be aware of
- Progressive retinal atrophy (crd3/PRA) — an inherited eye disease causing gradual vision loss; a DNA test is available and breeding dogs should be tested
- Hip dysplasia — a joint condition worth screening for, particularly given the breed's heavy, short-legged build
- Patellar luxation — slipping kneecaps, which can affect short-legged breeds
- Orthopaedic strain — the chondrodysplastic (dwarfed) leg conformation can predispose to joint and limb issues; keeping the dog lean helps
- Dental disease — common across breeds and managed with regular tooth brushing and checks
These reflect typical, size- and coat-related risks for dogs like the Glen of Imaal Terrier; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.

Bringing home a Glen of Imaal Terrier puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.
