Scent hound
A hunting dog bred to locate and pursue game primarily by following its scent, often over long distances and across varied terrain.
Olfaction: The sense of smell, produced when receptors detect and process airborne or dissolved chemicals. Scent hounds depend on olfaction to detect and distinguish the odor traces left by game.
Hound: A type of dog bred to help humans hunt, commonly by sight or scent. Scent hounds are one major kind of hound, distinguished by how they locate quarry.
Foxhound: A hound bred to pursue foxes by scent, typically in a pack. Foxhounds exemplify the pack-based pursuit that shaped many scent hound traditions.
Search and rescue dog: A dog trained to locate missing people in wilderness, disaster, or other search settings. Scent hounds' persistence can support searches across broad areas and difficult terrain.
Greyhound: A sighthound breed known for speed and pursuit of visible quarry. Its reliance on sight and rapid chase contrasts with a scent hound's trail-following.
Canine olfaction: The specialized smell system of dogs, with a large receptor area and strong capacity to discriminate odors. Its sensitivity helps explain how scent hounds follow faint trails over distance.
Sighthound: A hunting dog that locates and pursues quarry primarily by sight and speed. Sighthounds hunt by visual pursuit rather than by following an odor trail.
Beagle: A small scent hound developed for hunting hare and rabbit, often in packs. Its compact size and persistent nose suited foot hunters pursuing small game.
Tracking dog: A dog trained to follow a particular person's or animal's scent trail. This working role uses the same trail-following capacity central to scent hounds.
Bird dog: A hunting dog bred to locate or retrieve birds, often by pointing, flushing, or retrieving. Bird dogs commonly work through searching and signaling rather than extended scent trails.
