What specific subspecies designation confirms the Welsh Terrier's status within Canis lupus?

Answer

Canis lupus familiaris

The formal scientific classification that explicitly denotes the domesticated nature of the Welsh Terrier is the subspecies designation *Canis lupus familiaris*. While some sources might list only *Canis lupus* (the species level), the inclusion of the *familiaris* qualifier is crucial for specifying that this organism is a member of the domestic dog population, differentiating it from its wild counterparts within the *Canis* genus.
