v. following or pursuing something intently; looking into or investigating ruthlessly or relentlessly as does a bloodhound. A bloodhound is one of a breed of large,
keen-scented
dogs, approximately 26 inches (66
cm) in height and weighing about 90-110
pounds (41-50 kg). They are known for their wrinkled faces,
loose skin and very long ears. Their coats are commonly black-and-tan. The name refers to the
care taken in the original
breeding, that is to say they are
derived of ancestors of good blood. (Unmixed with other breeds.) Bloodhounds were formerly used to
track cattle and are now more commonly used to
track missing persons or criminals. Known to follow a human trail for more than 50 miles (80 km), they
track by
scent alone and can follow a
scent over dry land where no tracks are visible, swim across a river and pick the
scent up on the other side. When used by
police to recognize a
criminal, the
identification is accepted in a United
States court of
law.
