Basenji

The Basenji () is a breed of hunting dog created from stock that originated in Central Africa, including in the Republic of the Congo and other adjacent tropical African countries. The Fédération Cynologique Internationale places it in the Spitz and "primitive types" categories, while the American Kennel Club classifies it as a hound. The breed does not bark in the traditional manner of most dogs, rather vocalising in an unusual, yodel-like "talking" sound, due to its unusually-shaped larynx. This trait earns the Basenji its nickname of "barkless" dog, a similar feature seen and heard in the New Guinea singing dog.
