The Glen of Imaal is the most uncommon of Irish Terriers.
It is no surprise given the work they were bred to do, that the Glen can be a little stubborn. Friendly and faithful but determined to sometimes do their own thing, the Glen needs consistent handling.
Glens are one of those breeds that shed little and thus need to sometimes have haircuts. Their hair is rough and comes in three colors: blue, wheaten, and brindle.
And even though they are uncommon there is a rescue organization for Glens too; if you're willing to wait this is a breed you could potentially adopt.
Compact dogs with big personalities that are fun, and just gosh darn cute -- this is a breed that deserves to be more popular than it is.
