Few dogs sound like the New Guinea Singing Dog, whose eerie, rising howl has been compared to a yodel or whale song. It belongs to an ancient dog lineage closely related to the dingo, and genetic work suggests it descends from the highland wild dogs that still live in the mountains of New Guinea. Nearly every singing dog outside the island comes from a few animals collected in the mid-twentieth century and bred in zoos and by dedicated keepers.
Singing dogs are compact and foxlike, usually 20 to 31 pounds, with a broad head, erect ears and a bushy, white-tipped tail. They are curious, agile and intensely independent, more like a primitive breed or a cat than a typical companion dog. Many climb, dig, slip through gaps and hunt small animals with real determination. They are rare and best suited to experienced keepers prepared for an unusual animal.
