Bloodhound in 19th century clothes. The bloodhound was, according to legend, first bred ca. AD 1000 by monks at the St. Hubert Monastery in Belgium. Undoubtedly, its origins do reside in France, home of many of the modern Hound breeds. It is a scenthound, famed for its ability to follow a scent many days old, over vast distances. It possesses the keenest sense of smell of any breed of dog, as well as an extremely strong tracking instinct.
