This is such a cool-looking and cool-sounding dog. I first heard about the New Guinea Singing Dog when I was doing an art collage on dogs from around the world (you know, like the Scottish Terrier, the Afghan Hound, the Japanese Chin).
The New Guinea Singing Dog looks a lot like the Dingo. He has relatively the same build and a distinctive red coat. The few differences are that he generally has more white on his feet, face, and chest. And sometimes he has a little bit of black, or darkening, on his cheeks and/or muzzle.
This is a very old dog breed. In its native land, he might live as a wild scavenger dog or as a pet. Many are kept in zoos. You might see some in zoos here in the US.
So why is he called a singing dog? Well, he has a very distinctive sing-song howl. Here is a video of one singing.
