The New Guinea singing dog is a rare type of primitive canine that is found in the wild only on the island of New Guinea. Early travelers most likely brought the ancestors of this breed to the island where, isolated from the world, their descendants developed traits not found in other canids. Most distinctive is the dog's melodious howl, which earned it its name. The dog's uncertain origins and unique traits have complicated efforts to classify it.
