Why are dogs species of canine lupus?

Dogs are classified as Canis lupus familiaris, a subspecies of the gray wolf (Canis lupus), due to their shared ancestry and genetic lineage. They diverged from wolves thousands of years ago through domestication, which led to significant behavioral and physical changes. Despite these differences, dogs still retain many traits and instincts from their wild ancestors, linking them closely to the canine family. This classification reflects their evolutionary history and relationship with other canines.
