Feared extinct in its highlands habitat, the singing dog—whose name comes from its coyote-like howls—was last photographed in the wild 23 years ago.

At least 200 captive singing dogs live in zoos and as pets around the world, ancestors of a few wild dogs captured in the 1950s. But the animals—which resemble a domestic dog breed called the Shiba Inu—are severely inbred due to a lack of new genes.
