Etymology
Origin of bloodhound
First recorded in 1300–50, bloodhound is from the Middle English word blod-hound. See blood, hound 1
Explanation
Originating in Europe, the bloodhound is a large dog with a powerful sense of smell. Detectives and police officers may use a bloodhound when looking for a missing person or a criminal on the run. A bloodhound's powerful nose helps it follow scents and trails that are days old. Its long ears and wrinkled skin enhance its tracking abilities: With its nose to the ground, a bloodhound's ears drag along the terrain, stirring up and funneling particles to the dog's nostrils. And the wrinkly folds of a bloodhound's skin function as particle traps that keep the scents close at hand as the dog moves. In addition to being invaluable to police and search-and-rescue teams, bloodhounds are cherished pets due to their gentle and loyal nature.
