Scent hounds are a type of dog specifically bred for their exceptional sense of smell. They are often used in hunting and tracking because they can follow scents over long distances. Breeds like Bloodhounds, Beagles, and Basset Hounds are well-known examples of scent hounds, each with unique characteristics and abilities. These dogs have long ears and droopy skin, which help trap scent particles and enhance their olfactory capabilities. Scent hounds are typically friendly and social, making them great companions. However, their strong instincts can lead them to follow interesting smells, so they require proper training and supervision.
