The earliest confirmed domestic dog anywhere so far is from a burial site in Germany called Bonn-Oberkassel, which has joint human and dog interments dated to 14,000 years ago. The earliest confirmed domesticated dog in China was found in the early Neolithic (7000â5800 BCE) Jiahu site in Henan Province.

This led scientists to reclassify the domestic dog as Canis lupus familiaris, a subspecies of the wolf rather than a separate species.Domain-Eukarya Kingdom-Animalia Phylum-Chordata Subphylum-Vertebrata Class-Mammalia Order-Carnivora Family-Canidae Genus-Canis Species-Canis lupus Subspecies-Canis lupus familiaris.Domain Eukarya-Organisms have cells with a true nucleus and membrane-bound organelles.lassification.
