The dingo (Canis lupus dingo) is a free-roaming dog found mainly in Australia, as well as southeast Asia, where it is said to have its origins. It is currently classified as a subspecies of the grey wolf, Canis lupus. A dingo's habitat ranges from deserts to grasslands and the edges of forests. Dingoes will normally make their dens in deserted rabbit holes and hollow logs not too far from an essential supply of water. The dingo is the largest terrestrial predator in Australia, and plays an important role as an apex predator. However, the dingo is seen as a pest by sheep farmers due to frequent attacks on livestock. Conversely, their predation on rabbits, kangaroos, and rats is of benefit to cattle ranchers.
