Unlike many other terriers, they were bred to work mute to ground, going silently into dens rather than barking to alert their handlers. Glens are scruffy, sturdy, low-slung terriers, with a broad head, rose or half-prick ears and short, bowed legs and turned-out front feet. Their no-frills coat is wiry with a soft undercoat and is typically wheaten or shades of ‘blue’. Glen of Imaal terriers are lively and fearless little dogs, but considerably more laidback than most other terriers. They love getting outdoors and their strong hunting instinct can see them disappear on their own little adventures if owners are not careful! However, these are smart little dogs, which learn fast and respond well to early training. They are very people-orientated and are brilliant with children. They also do well with other dogs and household pets if raised with them. However, some can be dog-aggressive with unknown dogs, and will readily stand up for themselves if provoked. While Glens love activity, they are generally undemanding and are happy to relax alongside their owners.
