What group of dogs was bred specifically to follow scent trails?

The story behind the answer

Hounds are the group bred to trail game by scent—especially the “scent hounds” like Bloodhounds, Beagles, and Basset Hounds. Their long ears and loose facial skin help sweep and trap scent molecules toward the nose, and their extraordinary olfactory capacity lets them follow a trail hours—or days—old. Think “hounds hound the trail.”

By contrast, sighthounds (e.g., Greyhounds) hunt by speed and vision, gundogs (retrievers, spaniels, pointers) assist with finding and retrieving birds, and herding dogs manage livestock. Remember: hounds track; sighthounds sight; gundogs gun game; herders herd. This distinction reflects how humans shaped breeds for specialized tasks, turning dogs into precision tools for hunting, sport, and work across different terrains and prey.
