The Basenji is alert, energetic, curious and reserved with strangers. The Basenji is somewhat aloof with strangers, and tends to become emotionally attached to a single human. Basenjis may not get along with non-canine pets. Basenjis dislike wet weather, like to climb, can easily get over chain wire fences. Most Basenji problems involve a mismatch between owner and pet.
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. However, Basenjis are extremely intelligent and respond to training that is consistent and positive with plenty of treats. Basenjis do not respond well to punishment, such as yelling and hitting, which can cause them to utter a warning growl.
