The dog is a domesticated form of the wolf, a member of the Canidae family of the order carnivora. The domestic dog has been one of the most widely kept working and companion animals in human history.
The dog quickly became ubiquitous across culture across the world, and was extremely valuable to early human settlements. Dogs perform many roles for people, such as hunting, herding, protection, assisting police and military, companionship, and more recently, aiding handicapped individuals. Currently, there are estimated to be 900 million dogs in the world.
Over the 15,000 years span that the dog had been domesticated, it diverged into only a handful of landraces, groups of similar animals whose morphology and behaviour have been shaped by environmental factors and functional roles.
As the modern understanding of genetics developed, humans began to intentionally breed dogs for a wide range of specific traits. Through this process, the dog has developed into hundreds of varied breeds and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the withers ranges from a few inches in the Chihuahua to a few feet in the Irish wolfhound; colour varies from white through grays to black and browns from light to dark in a wide variation of patterns; coats can be short or long, course-haired to wool-like, straight, curly or smooth. It is common for most breeds to shed this coat, but non-shedding breeds are also popular.
