The Bloodhound is a large, heavily boned hound whose thin, loose skin hangs in deep folds about the head and throat, with long, low-set ears, pendulous lips and lower eyelids that show some of the haw. The short coat is black and tan, liver and tan, or red. By nature it is affectionate and gentle, somewhat reserved with strangers, and wholly absorbed once on a scent, giving tongue in a deep, resonant bay.
The Bloodhound's name is usually explained as referring to blooded hounds, meaning those of pure breeding kept by noble houses, rather than to any taste for blood. In Britain its numbers fell as faster hounds came into favour for hunting, and the breed was carried into the era of dog shows by a small number of breeders. The international breed standard names Belgium as its country of origin, reflecting its traditional link to the Saint-Hubert hound. The breed was developed to follow the scent of a single quarry, even along old trails, and has tracked people as well as game. It is still used by police and search teams to trace missing people, and in parts of the United States trailing evidence from Bloodhounds has been admitted in court.
