It is loyal and tends not to wander, and in fact prefers physical proximity to its owner. It makes an excellent companion and does well in obedience. Glens have character. They are thinking dogs, and quickly understand what their owners want. A verbal scolding is usually sufficient reprimand.
Good fences are the best way to prevent any problems.
We have found the Glen to be an easy dog to live with. It does not thrive in kennels, preferring a human environment where it can use its intelligence and enjoy its owner's companionship. It has few parallels as a weather-hardy, working dog. In obedience classes, instructors are repeatedly impressed with the Glens' intelligence, earnestness, and willingness to work. With daily exercise, the Glen has adapted well to even city and apartment life .
