Why do Glen of Imaal Terriers sit up?

Glen of Imaal Terriers “sit up” or “beg,” where they sit back on their hind legs with their front paws raised. This behavior is thought to have developed due to their role as turnspit dogs, which were used to run on a wheel that turned meat over a fire. Sitting up might have been a posture adopted for balance or rest when not in motion.

Another theory is that this behavior developed as part of their natural agility and desire to interact with people, as many terriers tend to be attention-seeking and clever. Today, it’s an endearing and charming trait of the breed.
