It is always risky to generalize about any group of living things, especially breeds of dogs. Exceptions always exist. There are, however, several character traits which it is fair to say the Glen of Imaal Terrier possesses. They are hardy and resilient--some of us would say "stoic”. They are inclined not to bark much.
   Indeed, they were bred to be silent when working. That being said, if other dogs in the household are prone to sounding off, a Glen will join the chorus. When they do bark, it is a surprisingly deep and resonant sound, suggesting a dog much larger than they are. For this reason alone, some people find them to be suitable watch (not guard) dogs. They tend to make their own exercise and are equally at home on acres of land or in an urban apartment. They love a good walk (not a jog as their short legs couldn't keep up), a romp in the park or through the woods, and especially love a good car ride. Reports of car sickness or drooling are rare.

  Glens are game. Other furry creatures are often seen as prey. They are terriers, after all. And like most terriers, that gameness can be expressed as aggressiveness towards other canines that they perceive as adversaries.
 
It has often been said that a Glen will rarely start a fight but is likely to finish it. Yet many Glens live happily in the company of other dogs...some even with cats, especially if they were raised together. Proper introduction, supervision, and instruction are required. Many Glens are not suited for the dog park, but make excellent loving pets.

Like many terriers, Glens can be stubborn and have an independent streak. They respond enthusiastically to praise and dramatically to a scolding. With time and patience they make great agility dogs.

Glens are inquisitive. Many Glen owners would say that their dogs are also naive about traffic. A fenced yard, and always walking a Glen on lead, is essential. Invisible fences will work only under supervision as the prey drive to chase the squirrel outdoes the jolt of the fence. Glens can be diggers, so ideal fencing should have a sound foundation. Caution should be taken around swimming pools. Though many Glens love the water, most are not strong swimmers due to their heavy weight and very short legs.


Glens tend not to be hyper. Many, in fact, could easily be considered bona fide "couch potatoes," yet they can be extravagantly silly and full of pluck, finding pleasure in the most peculiar (to us) preoccupations. Some entertain themselves by just running in circles. They are adoring of children, but it should be remembered that a 35 pound, well-muscled dog can easily knock over a young child. It is unlikely that such a youngster could control a Glen on a lead.

Simply put, Glens are most often quite easy to live with, and they are extremely easy to love. While not constantly demanding attention, they adore human contact and return the gesture with gentleness and forbearing.
