A hound is a type of dog that assists hunters by tracking or chasing the animal being hunted. It can be contrasted with the gun dog, which assists hunters by identifying the location of prey and/or recovers shot quarry. The hound breeds were the first hunting dogs. They have a powerful sense of smell, and speed.
There are three types of hound, with several breeds belonging to each type:
Sighthounds (also called gazehounds), which follow prey predominantly by speed, keeping it in sight. These dogs are fast and assist hunters in catching game (e.g., hares, elk, deer, foxes, rodents).
This may not include all hound-type dogs. The international kennel club association, the Fédération Cynologique Internationale, does not have a Hound Group and includes most hound-type dogs in Group 6, Scenthounds and related Breeds, and Group 10, Sighthounds.
