The quick, medium-sized Harrier pack hound was developed in medieval England to hunt hares. The Harrier is an outgoing and sociable dog that is bigger than the Beagle but smaller than the English Foxhound, another near relative.
Harriers are larger, more robust hounds than their little cousin, but smaller than the English Foxhound, a breed employed in their development. They resemble a Beagle with a gym membership. Harriers have the classic appearance of a working pack hound, measuring between 19 and 21 inches at the shoulder. They have a short, smart-looking coat, low-set, velvety ears, an irresistibly adorable face, and enough muscle and sinew to withstand a long day of hunting. A Harrier that is physically fit will move with a fluid, effective gait.
