Glen of Imaal Terrier · Terrier
The Glen of Imaal Terrier is a low, heavy-boned Irish earthdog from a remote valley in County Wicklow. It looks like a small shaggy dog and handles like a much bigger one: broad chest, bowed front legs, strong jaws and a calm, determined mind. Farmers kept it for vermin, fox and badger, and legend says it also turned the kitchen spit. At home it is usually quieter and more laid-back than many terriers — until it decides to dig, pull or take on a dog that challenges it. The honest plan is to respect the power, give the dig drive a safe outlet and protect a long back while the dog matures.
First, the point
Public histories place the breed in the Glen of Imaal, a remote valley in the Wicklow Mountains of eastern Ireland. Smallholders there needed a hardy, low dog that could deal with rats, foxes and badgers and earn its keep around the farm. Local stories also link the breed to turnspit work, running in a wheel to turn meat over the fire. The Irish Kennel Club recognised the Glen in 1934; the breed reached the Kennel Club register in Britain in 1975 and the AKC in 2004.
What I meet in homes is a dog that surprises people. It is often calmer and quieter than other terriers, happy to lie by the fire, and less likely to bark at every leaf. But it is strong for its size, can pull like a tractor, digs with real commitment and may not back down if another dog pushes it. Owners who expect a small lapdog are caught off guard; owners who expect a sharp, yappy terrier are pleasantly surprised.
My plan starts with three pillars. Strength management: loose-lead walking taught early, with a harness, before the dog is fully grown. Dig management: a proper dig box or scent games and supervised garden time. And body care: steady exercise without heavy jumping or stairs for growing puppies, plus a lean weight to protect the long back. With that, the Glen becomes a loyal, steady companion with a quiet sense of humour.
Breed history
History will not walk your dog, but it explains why Glens are so strong, dig with such focus and stay calm until they decide something matters.
Wicklow valley farms
Public accounts describe Glen of Imaal farmers keeping a short-legged, powerful terrier for vermin, foxes and badgers. The dog had to be quiet, determined and strong enough to hold its ground underground.
Local stories also tell of turnspit work: a dog running in a wheel to turn meat over the fire. Whether every Glen did this or not, it fits the breed’s steady, tireless character.
From a local farm dog to recognised breed
The Irish Kennel Club recognised the breed in 1934. The Glen remained rare outside Ireland for decades, joining the Kennel Club register in Britain in 1975 and the AKC in 2004.
Today most Glens live as companions. The strength, the dig and the determination remain, along with a calmer temperament than many terrier owners expect.
What the breed was bred for
In trainer terms, the breed was selected for a dog that works quietly, holds its ground and keeps going. At home that becomes strong pulling, serious digging and a dog that may not back down from a challenge — combined with calm, affectionate behaviour indoors.
Glens are usually food-keen and learn well with patient, consistent training. They can be slow to mature and may need time. Harsh handling tends to make them dig in their heels.

Life together
Daily life with a Glen is usually calm and affectionate. Expect steady walks, serious interest in holes and smells, and long naps. The main challenges are strength on the lead, digging and occasional disagreements with other dogs.
Most adults enjoy 40–60 minutes of steady walking with sniffing. Teach loose-lead walking early and use a harness; a grown Glen that pulls is hard to hold. Avoid long runs on hard ground for young dogs.
See loose-leash walking and walk length by age.
Set up a dig box or a corner of the garden with buried toys and treats. Celebrate digging there and supervise elsewhere. A Glen with a proper dig is far less likely to excavate the lawn.
Many Glens are fine with dogs they know but may not back down if challenged. Keep greetings short, on lead and optional. Parallel walks beat chaotic dog parks.
The harsh coat needs brushing and occasional hand-stripping. Teach calm handling of feet, ears and the body early. A Glen that accepts handling makes vet visits easier.
See puppy handling and nail trim ladder.
After a walk and some digging, most Glens settle easily. Teach place and reward calm. Keep them lean and avoid jumping on and off high furniture to protect the back.

Care and health themes
General awareness only. I am not a veterinarian. With Glens, owners often notice trouble first as stiffness or reluctance to jump, a limp, night-vision changes or weight gain. For red flags, leave this page and open when to call the vet.
A form of progressive retinal atrophy (PRA) is known in the breed, and DNA testing exists. Ask breeders about the parents’ status.
Hip and elbow dysplasia are discussed in the breed. Limping or stiffness needs a vet.
A long back and short legs need care: keep the dog lean and limit heavy jumping, especially in puppies.
Glens love food and gain weight easily. See body condition and rations.
Brush and hand-strip to keep the coat healthy and check for skin irritation.
Strong jaws still need dental care. See trainer and veterinarian.
Lines and types
No bloodline selling. Differences show in coat and build, but every Glen needs lead manners, dig management and care for its back.
Fits an owner who wants a quiet, sturdy companion and will manage strength and digging.
Fits an owner who wants a steady hiking partner and will train patiently.
Socialization windows
AVSAB-aligned in spirit: short, clean exposures at a distance the puppy can still eat, with hygiene while vaccines finish. See the puppy socialization schedule.
Introduce: name game, short handling sessions, loose-lead practice in the garden, dig box play, calm greetings.
Do not overload: stairs and jumping off furniture, rough play with big dogs, long walks.
Introduce: dogs at a distance where the puppy can still eat, short walks on varied surfaces, scent games, first grooming visits.
Do not overload: long runs on hard ground, chaotic dog parks, letting pulling become a habit.
Introduce: loose-lead walking around distractions, recall on a long line, polite greetings, stripping routines.
Do not overload: heavy jumping, letting the dog drag you to other dogs, harsh corrections.
Introduce: longer walks as the body matures, sports such as scent work, steady routines.
Do not overload: assuming the dog is fully mature too early, letting weight creep up.
Introduce: refresh lead and recall, keep dig outlets, yearly health checks.
Do not overload: ignoring stiffness or vision changes, skipping coat care.
Before you buy
Fit comes down to strength on the lead, digging, back care and how calm you want the dog indoors.

Mismatch risk
If you are torn between breeds
The Scottish Terrier shares the low, powerful build; the Soft Coated Wheaten shares the Irish farm-terrier roots. The Glen is the heavy-boned, quieter middle ground.
Glen of Imaal Terrier Low; about 12.5–14 in, roughly 32–40 lb.
Scottish Terrier Similar height; lighter and more compact.
Glen of Imaal Terrier Long body, bowed front legs, heavy bone.
Soft Coated Wheaten Terrier Taller, square, longer legs.
Glen of Imaal Terrier Often quieter than many terriers.
Scottish Terrier Alert and vocal when something matters.
Glen of Imaal Terrier Strong; needs a proper dig spot.
Soft Coated Wheaten Terrier Less earthdog focus; more bouncy greetings.
Glen of Imaal Terrier Harsh double coat; hand-stripping.
Soft Coated Wheaten Terrier Silky single coat; regular brushing and trimming.
Ownership without surprises
Costs depend on country, city and your choices. These are themes to plan for, not quotes.
PRA DNA status and hip and elbow screening of parents, plus regular vet checks.
Hand-stripping a few times a year and regular brushing.
Secure fencing and a dig box; Glens can dig deep.
Measured rations to keep the dog lean and protect the back.
Puppy class and lead-manner help while the dog is still small.
A well-fitted harness, long line and ramps or steps for furniture and cars.
The biggest long-term saving is a lean dog with good lead manners — strength and weight are what drive costs later.
Before day one at home
Glen puppies are sturdy, curious and food-keen. Prepare lead training, a dig box and careful exercise before day one.
Reward a loose lead in the garden before the puppy gets strong. See puppy leash training.
Limit stairs and jumping off furniture; use ramps where possible.
A sandpit with buried toys gives the paws a proper job.
Use part of the daily ration for training. See treat calories in the ration.
Out after sleep, meals and play. See potty training.
Overtired puppies get mouthy. Use enforced naps.
If the dog is already yours
Keep rules simple: loose lead on walks, dig only in the box, calm greetings with dogs and people, place after exercise. Reward each one generously.
Glens are food-keen and learn well, but they mature slowly and can be stubborn when pushed. Patient, consistent sessions work better than long drills or harsh corrections.
Management makes training work: a harness, supervised garden time and calm dog introductions. You stop the habit while new habits grow.
Load balance
Age, joint and back health, weight and weather all affect the right exercise. Stiffness, limping or vision changes need a vet check before more training.
Walks, scent work, digging and short training sessions all count. Long runs and heavy jumping do not suit a growing Glen.
A Glen that has walked, dug in its own box and practised a short lead lesson can pass another dog calmly and nap by the fire.
Loose lead before full strength
Start early, reward position by your leg, stop when the lead tightens and build distractions slowly.
Fit a comfortable harness so pulling does not strain the neck.
In the garden, reward the dog for being next to you on a loose lead.
Stand still the moment the lead goes tight and continue when it slackens.
Move to quieter streets, then busier ones, rewarding calm walking.
Several short lead lessons beat one long, frustrating walk.
One scene close-up
A strong, low dog with a determined mind can pull hard, and if pulling gets it where it wants to go, the habit grows. Pulling back only adds resistance.
Use a harness, reward the dog for being next to you, stop when the lead tightens and continue when it slackens. Practise in quiet places first.
If pulling comes with lunging at dogs, get help from a qualified professional.
Typical household scenes
A breed page is only a starting point; the fix depends on health, environment, and the dog in front of you. Each row opens a step-by-step guide.
Strength grows faster than lead manners.
Lawn and beds become excavation sites.
Will not back down if challenged.
Determined nose overrides the cue.
Strong jaws and possessive moments.
Grooming and vet checks become a struggle.
Food-keen dogs on short legs gain quickly.
Back, joint or eye concerns: vet first.
Practical view
“With a Glen, I teach the lead before the dog is fully grown, give the dig drive a legal box and protect the back. The result is a calm, steady companion that happens to be very strong.”
