Recent genetic study by Elaine Ostrander confirms that the Pekingese lapdog, bred in ancient China to fit inside the sleeves of a man's robe, is one of the oldest breeds of dog. For centuries, they could be owned only by members of the Chinese Imperial Palace. Similarly ancient are the lapdog ancestors of the modern breeds of Tibetan Terrier, Lhasa Apso, Pug, and Shih Tzu.
