'''Dogs''', colloquially known as "man's best friend", are a subspecies of [[wolf|wolves]] (given the scientific name Canis lupus familiaris), divided into a multitude of different breeds all capable of interbreeding (though in some cases, physical relations between representatives of two breeds are unlikely or problematic - Chihuahuas and Great Danes, for example). They are one of the most well-known domesticated species, with archaeological and historical records showing that they have lived in a mutually beneficial relationship with humans for upwards of ten thousand years; in Biblical times, they had already been coexisting with humans long enough for it to be regarded as the natural order of things.

It is likely, based on genetic evidence, that the oldest breeds of dog originate in [[Asia]], and that thus the domestic dog originated there; similar research has shown that it is probable that the first settlers of the [[America]]s brought dogs of some sort with them.
