Profile description
The Glen of Imaal Terrier is a small but powerful Irish terrier developed in the Wicklow Mountains for controlling vermin and working around farms. Most adults stand around 32 to 36 centimetres tall and weigh approximately 14 to 18 kilograms. The breed has a long, low body, bowed front legs, broad head and a medium-length harsh coat.
Common colours include wheaten, blue and brindle. Glens are typically courageous, intelligent, affectionate and quieter than many other terriers. They often form close bonds with their families and can be calm indoors when adequately exercised. Their working history gives them determination, physical strength and a strong prey drive. A functionally built Glen of imaal terrier should show balance and comfortable movement rather than an exaggerated interpretation of the physical features for which the breed is known.
They may chase small animals, dig or become assertive with unfamiliar dogs. The breed is slow to mature and can retain a playful, stubborn personality into adulthood. The Glen of Imaal Terrier is best suited to owners who can provide moderate exercise, patient training, secure fencing and careful protection of the dog’s long back and developing joints. Independence in the Glen of imaal terrier should not be confused with an inability to learn, although motivation and repetition must be managed more thoughtfully than with a highly handler-focused dog.
Appearance is only one part of deciding whether a Glen of imaal terrier is a suitable long-term companion. Living space alone does not determine suitability for a Glen of imaal terrier; access to companionship, purposeful activity, rest and consistent handling is more important than the size of the property.

Care requirements
Routine Glen of imaal terrier care combines moderate daily exercise, careful weight management and protection of its spine and joints. Several steady walks, scent games and controlled play sessions are appropriate. Build the Glen of imaal terrier's weekly routine around several forms of movement rather than repeating one route, and include lower-intensity recovery after unusually demanding activity. Mental work for a Glen of imaal terrier can come from scent searches, food puzzles, cooperative handling and short training problems matched to the dog's confidence and physical ability.
Puppies should avoid repetitive jumping, frequent stairs and heavy impact because their bones mature slowly. Off-leash activity should occur only in secure areas because the breed may chase wildlife or follow scents. Training should use positive reinforcement, food rewards and short, varied sessions.
The harsh coat should be brushed and combed several times a week and periodically hand-stripped or professionally groomed. Hair around the ears, feet and underbody may require tidying. The Glen of imaal terrier needs frequent tooth brushing, short nails and routine ear checks for irritation.
Food portions should maintain a lean body condition because excess weight increases pressure on the spine and short legs. Regular veterinary examinations should monitor eyes, hips, elbows, knees and back health. Owners should seek prompt veterinary care for pain, weakness or changes in movement. Owners should establish the Glen of imaal terrier's normal appetite, breathing, movement, sleep and social behaviour so a persistent departure from that baseline can be investigated promptly. Care requirements for a senior Glen of imaal terrier should be reviewed as mobility, senses and recovery change; shorter sessions, better footing and easier access can preserve independence without removing enrichment. Seek veterinary advice promptly if a Glen of imaal terrier develops breathing difficulty, collapse, severe pain, repeated vomiting, inability to urinate, sudden weakness or a rapidly worsening change in behaviour.
