The Glen of Imaal Terrier is a medium-sized Irish working terrier: long-bodied, powerful, and lower to the ground than many terriers. It may suit owners prepared for moderate exercise, short reward-based training, a harsh double coat that needs regular brushing and periodic stripping, and supervision around children and other animals. Breed tendencies are not guarantees, so ask about an individual dog’s temperament and review documented health tests when choosing a puppy.
Glens are often described as less excitable than many terriers, yet they retain a bold, spirited, independent character and interest in small prey. Their growing front legs merit particular care: follow your veterinarian’s guidance on a puppy’s activity and contact a veterinarian promptly if the puppy limps.

Glen of Imaal Terrier temperament
The breed standard describes a Glen as spirited and courageous when called upon, but otherwise gentle and docile. The AKC describes Glens as less excitable than most terriers while retaining a bold, spirited character. These are breed-level tendencies, not guarantees about any individual dog.
Glens are smart and trainable, but their independent terrier character can make repetitive drills boring. They may follow an interesting scent or focus on small prey instead of a handler’s request. Training works best when it is short, varied, rewarding, and worthwhile from the dog’s perspective.
Are Glen of Imaal Terriers good with children?
They can be family companions, but no breed makes unsupervised child interaction safe by default. Adults should supervise interactions, teach children not to climb on, corner, disturb, or take things from the dog, and give the dog a quiet retreat. Ask a breeder or rescue about the individual dog’s temperament and response to household activity.

Are they friendly with other dogs and small animals?
Do not assume every Glen will welcome every unfamiliar dog or live safely with small animals. The breed’s working-terrier background and interest in small prey make careful introductions, supervision, and secure management sensible. Reward-based training can help build useful skills, but it cannot guarantee that a dog will ignore prey.
Exercise: moderate needs, careful conditioning
The AKC characterizes the Glen’s exercise needs as moderate. Walks, supervised play, and scent or training games can provide movement and enrichment. Adjust activity to the individual dog and avoid making repetitive high-impact exercise the goal.
Rank #2
Give puppies short, fun leash walks and opportunities for self-paced play in a house or fenced yard. AKC breed-care guidance cautions against undue stress on growing front legs, including jumping from furniture and steep stairs. It notes that some breeders avoid these activities until at least nine months and that growth plates may close between nine and twelve months. This is breed-care guidance, not a universal veterinary timetable; ask your puppy’s veterinarian what is appropriate for its development.
Puppy exercise rules
- Favor controlled, self-paced play and short walks over forced running.
- Limit jumping from furniture or other heights and repeated use of steep stairs while the puppy grows.
- Do not assume a puppy’s enthusiasm means its front legs are ready for strenuous activity.
- If a puppy limps, restrict activity and contact a veterinarian promptly rather than trying to diagnose or treat the problem at home.
Training and socialization
Positive reinforcement suits the Glen’s intelligence and independence. Reward the behavior you want with food, play, praise, or access to an activity the dog values. Keep lessons short and vary the task; the AKC recommends puppy classes, early socialization, and brief sessions because repetitive training can bore Glens.

Prioritize these skills
- Name response and check-in: Reward the dog for looking toward you before distractions become overwhelming.
- Loose-leash walking: Reinforce a workable walking position without expecting the dog to ignore every scent.
- Recall: Build it gradually with rewarding practice, then use a leash, long line, or secure area when needed.
- Leave it and trade: Teach useful alternatives for unsafe objects or situations.
- Settle: Help the dog learn to relax on a mat or bed after activity.
- Cooperative handling: Practice calm paw, ear, mouth, and body handling before grooming or veterinary care becomes urgent.
Expose puppies gradually and positively to people, stable dogs, surfaces, household sounds, car travel, grooming equipment, and veterinary-style handling. Socialization is not a requirement to greet everyone; it is an opportunity to learn that unfamiliar experiences can be safe while the handler maintains distance and control.
Grooming a Glen of Imaal Terrier
The Glen’s weather-resistant double coat has a harsh outer layer and soft undercoat. The AKC recommends moderate weekly brushing to help prevent matting, especially around the furnishings. A slicker brush can help with brushing; check the furnishings around the ears, neck, legs, and belly for tangles.
Traditional coat care includes hand-stripping two or three times a year. Stripping removes mature outer-coat hair and helps maintain the rough terrier texture. If you are new to the technique, ask an experienced groomer or breeder to demonstrate it; a Glen breeder’s guidance advises waiting until long outer hairs come out easily.
A dog grooming stripping knife may be useful for an experienced owner, but it is optional and does not replace instruction. A slicker brush for wiry coats can help find tangles in the furnishings. Work gently and stop if the dog is distressed or the coat is pulling.

- Weekly: Brush the coat, check the furnishings, inspect the ears, and look at the skin for irritation or unusual changes.
- As needed: Trim nails and check paw hair and pads.
- Frequently: Brush the teeth with dog toothpaste.
- Two or three times a year: Arrange hand-stripping or do it only if properly trained and the dog is comfortable.
A small sturdy dog grooming table is an optional convenience that may make home grooming easier. Use a non-slip surface, supervise the dog directly, and never leave it unattended on an elevated table.
Feeding and weight management
Feed a high-quality, complete food appropriate for the Glen’s life stage and activity level, and provide fresh water. The AKC recommends moderation with treats because excess treats can contribute to obesity. Serving charts are starting points; ask your veterinarian or breeder about weight or diet concerns.
Measure meals, count training treats, and assess body condition regularly. Keeping a Glen lean avoids unnecessary weight burden. Ask your veterinarian for guidance if the dog gains or loses weight unexpectedly or has a suspected food intolerance.
Dental, ear, nail, and preventive care
Brush teeth frequently with toothpaste formulated for dogs and check ears regularly for debris or excess wax, as the AKC recommends. A dog toothbrush and toothpaste can make a consistent home routine easier. Introduce handling gradually and ask a veterinarian to assess a painful, inflamed, severely dirty, or unusually odorous ear.
Tailor preventive care to geography, lifestyle, age, and veterinary advice. Discuss examinations, vaccinations, parasite control, identification, dental care, and monitoring of mobility, vision, skin, ears, and body condition.
Glen of Imaal Terrier health concerns
The AKC lists hip dysplasia and eye disease, including cone-rod dystrophy (PRA-crd3), as breed health considerations. Its recommended breed-club tests include hip and elbow evaluations, an ophthalmologist evaluation, a degenerative myelopathy common-variant DNA test, and PRA-crd3 DNA testing. Breed-club guidance also highlights screening for these conditions. Screening recommendations are not a diagnosis, and a genetic test addresses only the variant it evaluates; no test guarantees overall health.

Health testing when buying a Glen puppy
The Glen of Imaal Terrier Club of America’s health statement says breeding sires and dams should have hip and elbow evaluations, an examination by an ACVO ophthalmologist beginning at age two and repeated every two years until age eight, and crd3 testing. It recommends reporting results to OFA and directs puppy buyers to OFA or CHIC records. Ask to verify the parents’ identities and review their actual results rather than relying on a verbal assurance.
Ask for results for both parents, and ask:
- Have the parents had the recommended hip, elbow, eye, and crd3 evaluations?
- What health problems have appeared in this line?
- How are puppies raised, handled, socialized, and introduced to grooming?
- What veterinary records, registration documents, contract, and identification accompany the puppy?
- What happens if the owner cannot keep the dog?
Health screening helps inform breeding and puppy-buying decisions, but it is not a guarantee that an individual dog will remain disease-free.
Finding a responsible breeder
Availability can vary by country and year, so finding a suitable litter may require patience. A responsible breeder should offer a written contract, veterinary records, transparent pedigree information, and verifiable health-test documentation. Ask about the parents’ temperaments and health history, and expect the breeder to ask questions about your home and plans for the puppy.
Be cautious of a seller who will not show test results, pressures you to send a deposit immediately, cannot explain the parents’ temperaments, or dismisses questions about health screening. The goal is to find a compatible dog from a breeder who takes health and lifelong placement seriously.
