Despite the bloodhound’s name, it is not vicious and has no special fondness for blood. This big, saggy-skinned dog is so-named because it is a blooded (pedigreed) hound. Its lineage dates back to very early records in Europe. The bloodhound has the best sense of smell of all dogs.
Originally bred for tracking game by sent, this will-mannered dog is now used mostly to track fugitives or lost persons. A bloodhound can track down a person who is lost in the woods by sniffing something that belongs to that person and picking up his/her trail.–Dick Rogers
