Domestic dogs are a popular household pet. Breeds of this animal include the Siberian Husky, German Shepherd, Chihuahua, Great Dane, Dachshund, Cocker Spaniel, Afghan Hound and Rottweiler. The dog can also be used to guard things, to herd animals, to go hunting with and so on. Unlike cats, dogs can't fully retract their claws. They are descended from wolves and were supposedly domesticated when a forest-dwelling tribe discovered an orphaned wolf pup and took it in, which supposedly sparked the dog's domestication.
