The short-eared dog (Atelocynus microtis) is found only in and around the Amazon rainforest. For decades, scientists had almost no firsthand information about this elusive species. It hides so well that even experienced Amazon researchers can go years without seeing one.

With its slender build and low posture, it resembles a jaguarundi more than a typical dog. Its ears are short and rounded, unlike the upright shape seen in foxes or wolves. It has a bushy tail and a thick, usually dark coat.
