A Bloodhound's sense of scent is so acute and exact that it may be used as evidence in court. Their scent membranes allow dogs to distinguish odours at least a thousand times better than humans. Bloodhounds are frequently employed to locate missing people and criminals. They can follow traces that are almost 300 hours old and can go 130 miles on a path.
