Basenjis do not bark, but instead emit a very distinctive type of yodel.
About the Basenji
Basenjis are lightly built and fine-boned dogs with long legs, always well balanced, lively and intelligent.
Although relatively independent and aloof with strangers, the Basenji is known to be affectionate with their family. These remarkably clean dogs are active and graceful in motion, where they exhibit long, smooth strides.
