The Bloodhound is a large scent hound, originally bred for hunting deer, wild boar and, since the Middle Ages, for tracking people. It also seems that from the earliest times the Bloodhound was used to track people. There are stories written in Medieval Scotland of Robert the Bruce (in 1307), and William Wallace (1270–1305) being followed by 'sleuth hounds'. Having lost a scent, a good bloodhound will stubbornly cast about for long periods, if necessary, in order to recover it. The bloodhound is handled on a tracking harness, which has a metal ring above the shoulders, to which a leash is attached, so that the hound's neck is not jerked up when the leash becomes taut, as it would with a collar. The leash is at least long enough to allow the hound to cross freely in front of the handler, some handlers preferring quite a short leash, giving better communication with the hound, others liking something longer, maybe twenty or thirty feet.
