Glen of Imaal Terrier
Forty pounds of dog on legs barely a foot long - the Glen of Imaal Terrier is built low, heavy and startlingly strong for the size, and content to lie by the fire between outings. They are affectionate at home and patient with children. The dealbreakers are honest ones: a long back and heavy body that make stairs and jumping a lifelong management job, and a prey drive that puts small pets permanently out of reach.
Pup Height
12.5-14 in
Pup Weight
32-40 lb
Longer than tall and startlingly heavy for the height - forty pounds on a dog barely over a foot at the shoulder, which is why they are described as a big dog on short legs rather than a small dog. The coat is a harsh medium-length outer over a soft undercoat, in wheaten, blue or brindle. Front legs turn out slightly, which is correct rather than a fault. One of four Irish terrier breeds and much the rarest. Source: AKC breed standard.

Your pup, at a glance
What’s Life With This Pup Really Like?
High. They are affectionate and genuinely calm indoors, happy to settle against their people once the day's walk has happened.
Very good. Sturdy, patient and far less snappy than most terriers - solid enough to cope with family life.
Difficult. Reasonable with dogs they know, and a real risk to cats, rabbits and anything small - the earth terrier's prey drive is fully intact.
Low, and remarkable for a terrier. They were bred to work silently underground and they stay quiet at home.
Moderate. An hour suits them and they switch off indoors properly afterward.
Low. The harsh coat sheds lightly, and stripping removes most of what would otherwise drop.
Game and good-humored. They enjoy digging, tug and scent work without the frantic quality of most terriers.
Low.
Moderate. Bright and quick, and stubborn enough that they decide whether it is worth doing.
Moderate. Alert and aware of arrivals, and too quiet to be much of an alarm - the warning is a posture rather than a bark.
Moderate. Twice-weekly brushing plus stripping a couple of times a year, and the skilled part is hard to source.
High. Apartment or house, city or country - they adapt easily, provided the stairs are managed and small pets are not part of the household.
Lifestyle fit
Could This Be Your Best Breed?
Glens suit an apartment or a house equally well, an owner who finds stubbornness funny rather than infuriating, and a home without cats or rabbits in it. They are inexpensive for a terrier at $1,300 to $2,200 a year, ask for a brush twice a week plus hand-stripping, and commonly reach twelve to fifteen. A cat or a rabbit in the house ends the conversation, and a Glen asked for crisp obedience will simply consider the request.
Living Space
Apartment or house both work. They are genuinely quiet for a terrier - the breed was bred to work silently underground - so the usual small-dog noise problem does not apply. Stairs are worth managing given the build.
Pup Experience
Manageable for a first-time owner who understands terriers. Glens are calmer and less reactive than most of the group, and they are still stubborn, strong for their size and hard-wired to go after small animals.
Daily Pup Time
Forty-five minutes to an hour of walking and play with something to think about. Grooming is a brush twice a week plus hand-stripping a couple of times a year.
Allergies & Coat
The Glen of Imaal Terrier scores 3/10 for shedding and 2/10 for drooling. No dog is truly hypoallergenic. The allergens come from dander and saliva, and a coat that sheds this little leaves far less of them on your furniture, floors, and clothes.
Quirks & challenges
The Not-So-Easy Stuff
Serious Prey Drive
Bred to face badger underground. Cats, rabbits and small pets are a real problem, not a training gap.
Stubborn by Design
They weigh a request rather than obeying it. Repetition without reward gets very little.
Long Back, Heavy Body
Forty pounds on short legs. Stairs, sofa jumps and extra weight all load the spine.
They Dig Properly
An earth-working terrier with the instinct intact. Give them a sanctioned spot or lose the beds.
Coat Needs Stripping
Hand-stripping keeps the harsh texture, and few groomers do it. Clipping softens it permanently.
Genuinely Rare
A few hundred a year worldwide. Expect a long waiting list and a very small gene pool.

Health Risks
Conditions this breed is prone to.
A breed-specific form, PRA-crd3, degenerates the retina until the dog is blind, usually beginning in middle age. There is no treatment and there is a DNA test developed for this breed - tested parents remove the risk entirely, so ask for the certificates.
The hip joint develops loosely so the ball wears in the socket instead of gliding, leading to arthritis. The heavy body on short legs puts real load through the joints - both parents should have scored hips.
The discs between the vertebrae bulge or rupture and press on the spinal cord, causing pain and sometimes hind-leg weakness. A long back carrying forty pounds is built for it; keeping them lean and limiting repeated jumping does most of the prevention.
Worth listing as a health condition rather than a habit. They are food-keen with modest exercise needs, and every extra pound feeds directly into the back and hip problems.
Allergic skin disease causing itching and recurrent infections appears in the breed. Managed with diet and medication over the dog's life rather than cured.
Worth listing on its own. With only a few hundred puppies registered worldwide each year, genetic diversity is narrow, which makes the individual breeder's testing more informative than breed-level statistics.
Insurance & Health Coverage
A reasonably healthy breed, so the case for cover is mostly the ordinary one plus the back.
Disc disease in a long-bodied, heavy-set dog is common enough to treat as a real possibility rather than bad luck. Spinal surgery runs into several thousand dollars with rehabilitation afterward, and it arrives suddenly. Insure before any back episode is on the record, because once it is there insurers exclude the spine - which removes exactly the cover you wanted.
PRA-crd3 is congenital, so no policy pays for it - but this breed has its own DNA test, and a breeder who has used it removes the risk before you bring one home. On that one the paperwork is worth more than the insurance.

Care needs
The Daily Routine
Grooming
A harsh medium-length coat over a soft undercoat that needs a thorough brush twice a week, with hand-stripping a couple of times a year to keep the texture. Clipping is easier and permanently softens the coat, so decide which you want before you start - and find a groomer who can strip before the puppy arrives, because few can. Ears and nails as usual.
Exercise
Forty-five minutes to an hour daily of level walking and play, with earthdog work and scent games to occupy the terrier brain. Keep it off repeated stairs and high jumps given the spine.
Food & Weight
Two measured meals. They are compact, heavy dogs with a long back, so extra weight lands precisely where it does the most harm - the ribs should be easy to feel under the coat.

If This Isn’t Quite the One
Cesky Terrier
The closest match - another long, low, stripped-or-clipped terrier with an unusually calm temperament for the group and a similarly small gene pool. The Cesky is lighter and more sociable with other dogs; the Glen is heavier and quieter.
Dandie Dinmont Terrier
A comparable long-backed working terrier with the same disc-disease considerations and the same skilled-grooming problem. The Dandie has a far deeper bark; the Glen is the silent one.
