Beagling is mainly the hunting of hares and rabbits by beagles using their strong sense of smell. A beagle pack is usually followed on foot, but in a few cases mounted. Beagling is often enjoyed by 'retired' fox hunters who have either sustained too many injuries or lost the agility to ride horseback, or who enjoy the outdoors and the camaraderie of the hunt. It is also traditionally a way for young men and women to learn how to handle hounds on a smaller scale before they go on to hunt with foxhounds.

The beagle is a breed of small scent hound, similar in appearance to the much larger foxhound. The beagle was developed primarily for hunting hare, known as beagling. Possessing a great sense of smell and superior tracking instincts, the beagle is the primary breed used as a detection dog for prohibited agricultural imports and foodstuffs in quarantine around the world. The beagle is a popular pet due to its size, good temper, and a lack of inherited health problems.
