A lap dog or lapdog is a dog that is both small enough to be held in the arms or lie comfortably on a person's lap and temperamentally predisposed to doing so. Lapdog is not a specific breed, but a generic term for a type of dog that is small in size and friendly towards humans. Lap dogs historically have been kept in many societies around the world by individuals with the resources to support a non-productive animal, and a lifestyle which allows for much contact with the dog. They are docile companion animals with no working function other than companionship. Genetic analysis reveals that lapdogs are among the earliest specific types of dogs to live with people. Today, most lapdog breeds fall into the toy breed group. Additionally, the term "lapdog" is also used to refer to a person, organization or country controlled by another who is stronger. Appearance Some lapdogs have been bred for extremes of small size, such as the Russian and Mexican varieties shown below. Anatomically, lapdogs show distinct differences from their full-sized counterparts. The skull of the immature Russian lapdog from an 1861 specimen (possibly an ancestor of the Bolonka) is approximately the size of a table-tennis ball and shows the relatively short muzzle and high forehead. Many lapdogs are bred to retain puppy-like traits (neoteny) such as folded ears. Body proportions may also have changed, resulting in relatively shorter legs and larger heads. They may also have traits that resemble human babies: size and weight, high forehead, short muzzle and relatively large eyes. Although selective breeding for such traits can have detrimental effects on tear ducts, dentition, and breathing, such traits also serve to cause pet owners to derive more satisfaction from their pet relationship, as the pet owners may view dogs with this appearance as surrogate babies. History In addition to their being kept as a pet and providing warmth, lap dogs have been fashion accessories and status symbols, and even to attract fleas away from their owners. 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.
