* Domain: Eukarya (both are eukaryotic organisms)
* Kingdom: Animalia (both are animals)
* Phylum: Chordata (both have a notochord at some stage of development)
* Class: Mammalia (both are mammals)
* Order: Carnivora (both are carnivores)
* Family: Canidae (both belong to the dog family)
* Genus: *Canis* (both are in the *Canis* genus)
However, they diverge at the Species level:
* Gray wolves: *Canis lupus*
* White shepherds: *Canis lupus familiaris* (domestic dogs are considered a subspecies of the gray wolf)
This means that gray wolves and white shepherds are very closely related, being the same species but different subspecies.
