What is the prevailing scientific subspecies designation for the Welsh Springer Spaniel?

Answer

Canis lupus familiaris

The prevailing scientific classification system identifies the domestic dog, including the Welsh Springer Spaniel, not merely as its own species but as a subspecies of the grey wolf. The specific designation reflects its direct evolutionary descent from *Canis lupus*. While *Canis familiaris* has been used historically, the current consensus acknowledges this close genetic link, placing the breed formally under *Canis lupus familiaris*. This hierarchical naming convention is essential in biology to reflect shared ancestry and differentiation within a broader species grouping.
