Dusicyon avus is an extinct species of canid native to South America during the Pleistocene and Holocene epochs. It was medium to large, about the size of a German Shepherd. It was closely related to the Falkland Islands wolf (Dusicyon australis), which descended from a population of D. avus. It appears to have survived until very recently, perhaps 400 years ago.
Dusicyon avus was around the size of a coyote, and was morphologically similar to jackals, suggesting a niche similar to both.
