Glen of Imaal Terriers are intelligent and independent, with a working-dog mindset. Training should begin early using reward-based methods and clear boundaries. They’re less reactive than other terriers, but still need early socialization with dogs and people to ensure balance.
Their medium-length, wiry coat needs weekly brushing and occasional hand-stripping to keep it tidy. Health issues are relatively few, though some Glens may experience hip dysplasia, progressive retinal atrophy, or allergies. This breed thrives in homes where they can be both mentally and physically engaged, but not overstimulated.
