Dogs have long been used as companions for outdoor sports, such as hunting and chasing anything from pheasants, ducks, rabbits, and foxes, etc. With their unparalleled tracking skills, sharp eyes and keen sense of smell; many hunters rely heavily on their canine counterparts. Dogs have been used to track raccoons in the dead of night, to pick out the imperceptible trails of their prey, or startle brush-bound bird foul into flight.
For example hounds are dog breeds that are used as trackers: and are categorized as sight hounds (such as Whippets, who spot and stalk prey), and scent hounds (such as Coonhounds or Blood hounds who track prey based on scent).
Another branch of hunting dogs are called "gun dogs" which are used to point or identify the prey's location, and then retrieve it once the animal has been shot. All retrievers (such as Labradors) are useful for fetching birds; pointers (such as German Short-Hair Pointers) identify and locate prey, water dogs (such as Poodles) swim fast and retrieve from the water; setters and spaniels (like the English Springer Spaniel and Irish Setter) have accompanied game hunters for hundreds of years; and even the All-American Beagle has been known to fetch rabbits after the hunters have made their kill.
