Glen of Imaal Terrier
Their bark is deep and authoritative, like that of a much larger dog, and they are said to be good watch dogs.
As terriers, Glens can have a stubborn streak, but they respond well to a firm hand and can withstand correction when necessary. They are intelligent, learn quickly, and socialize easily. They are typically fearless and loyal, and are superb with people, including children. However, some can be dog-aggressive, especially when provoked.
