The New Guinea Singing Dog is said to be one of the rarest breeds in the world. The breed has a fox-like appearance and is known for its characteristic ability to vary the pitch of its howl. They exhibit a structural flexibility that allows for them to squeeze through any space that will fit their head. While they can be domesticated, the New Guinea Singing Dog is not recommended as a pet for most people. They require firm leadership and exhibit wild dog tendencies such as an extreme hunting drive and a desire to roam and explore. They are rare in New Guinea but can be found in zoos across the world.
