breed of hound dog known for being the best tracking dog in the world because of its exceptionally keen sense of smell and its persistence; coat is short, tough, and slightly shiny; it can be black and tan or red and tan, sometimes with some white mixed into either combination; very long face, droopy jowls, wrinkled brow, and watery eyes give this breed a long-suffering look; ears are lobular, long, and folded; tail is long, thick, and carried somewhat upright when dog is on the scent; deep hazel to yellow eyes are deeply sunken and lower lid is pulled down by jowls; adult stands 23–27 in. (58–69 cm) tall at shoulders and weighs 80–110 lbs (36–50 kg); also called St. Hubert hound (especially in Belgium and France) because its ancestry can be traced to the monastery of St. Hubert in Belgium; once also called Segusius; very docile demeanor; can discern a cold trail and persistently follow it for many hours, thus favorite of law enforcement officers; though it has a melodious bark, it is silent while tracking; reputation for viciously attacking quarry is unfounded: it is more likely to lick and slobber the quarry once it is tracked down; introduced into England when Normans conquered France in 1066 and has been associated with that country ever since,
