What is the formal scientific species designation provided for the domestic dog?
Answer
*C. familiaris* or *C. lupus familiaris*.
The Linnaean hierarchy confirms that all domestic dog breeds, irrespective of coat color, size, or registry status, fall under the same scientific species classification. The established scientific hierarchy for the domestic dog lists its species designation as either *C. familiaris* or *C. lupus familiaris*. This classification system places them firmly within the Genus *Canis*, the Family Canidae, and the Order Carnivora, confirming that variation between a white shepherd and a sable shepherd is purely intraspecies variation, analogous to variations within other domesticated species.
