The Bloodhound is a large scent hound, originally bred for hunting deer, wild boar and, since the Middle Ages, for tracking people. This breed is gentle, and is tireless when following a scent. Because of its strong tracking instinct, it can be willful and somewhat difficult to obedience train and handle on a leash. Bloodhounds have an affectionate and even-tempered nature with humans, making them excellent family pets. In Medieval hunting, the typical use of the Bloodhound was as a 'limer', or 'lyam-hound', that is a dog handled on a leash or 'lyam', to find the hart or boar before it was hunted by the pack hounds (raches). It was prized for its ability to hunt the cold scent of an individual animal, and, though it did not usually take part in the kill, it was given a special reward from the carcass.
