A lap dog is a dog that is small enough to stand in the arms or lie comfortably on a person’s lap and temperamentally predisposed to do so. Bichons are not a specific breed, but is a generic term for a small dog type and friendly disposition.
Bichons historically have remained in many societies throughout the world by individuals with leisure time, as tame company animals no function other than the company. Genetic analysis reveals that bichons are among the first specific types of dogs to live with people. Today, most of the doggy breeds fall into the toy group breed.
Some bichons have been bred for the small extreme size, such as the Russian and Mexican varieties listed below. Anatomically, bichons show distinct differences in their full-size counterparts. The skull of an immature Russian lapdog from a sample of 1861 (possibly an ancestor of Bolonka) is about the size of a tennis ball table and shows relatively short nose and high forehead. Many bichons are bred to preserve the type of puppy traits (neotenia) such as folded ears. The proportions of the body may also have changed, giving relatively short legs and large heads result. They can also have traits that resemble human babies: height and weight, high forehead, short snout and relatively large eyes. Although selective breeding of these traits can have detrimental effects on the tear ducts, teeth and breath, these traits also serve to ensure that pet owners get more satisfaction from their pet relationship, Pet owners can see dogs with this appearance as surrogate babies.
