The Basenji is a breed of hunting dog. The Fédération Cynologique Internationale places the breed in its group five (spitz and primitive types), and the United Kennel Club (US) places the breed in its Sighthound and pariah group. Basenjis share many unique traits with pariah dog types. Basenjis, like dingoes, New Guinea singing dogs and some other breeds of dog, come into estrus only once annually—as compared to other dog breeds, which may have two or more breeding seasons every year. Both dingoes and Basenji lack a distinctive odor, and are prone to howls, yodels, and other vocalizations over the characteristic bark of modern dog breeds. Several attempts were made to bring the breed to England, but the earliest imports succumbed to disease. The title character of the 1954 novel Good-bye, My Lady, by James H. Street, is a Basenji (female).
