Dogs (scientific name ''Canis lupus familiaris'') are a subspecies of [[wolf|wolves]], divided into a multitude of different breeds all in principle capable of interbreeding (though in some cases, physical relations between representatives of two breeds are unlikely or problematic - Chihuahuas and Great Danes, for example).
