Canis lupus dingo

The dingo (Canis lupus dingo) is a free-ranging dog found in Australia. Its exact ancestry is debated, but dingoes are generally believed to be descended from semi-domesticated dogs from East or South Asia, which returned to a wild lifestyle when introduced to Australia. It and the dog are classified as a subspecies of Canis lupus in Mammal Species of the World.

The taxon dingo always refers to the native dog found in Australia, but may at times also refer to other dogs native to peninsular and island southeast Asia and neighboring regions, such as the New Guinea singing dog (halstromi). It has variously been considered a species of the dog genus (Canis dingo), a subspecies of gray wolf (Canis lupus dingo), and an invalid taxon or taxonomically synonymous with Canis lupus familiaris.
