It was bred from stock that originated in central Africa. Most of the major kennel clubs in the English-speaking world place the breed in the hound group—more specifically, in the sighthound type. Basenjis are small, short-haired dogs with erect ears, tightly curled tails and graceful necks. They can also come in trindle, which is a tricolor with brindle points, a rare combination. Basenjis often stand on their hind legs, somewhat like a meerkat, by themselves or leaning on something; this behavior is often observed when the dog is curious about something. Basenjis have a strong prey drive. According to the book The Intelligence of Dogs, they are the second least trainable dog, when required to do human commands (behind only the Afghan Hound).
