I think most are fine if properly socialized. Mine have varied from friendly to aloof, with my last one being somewhat untrustworthy and requiring supervision, particularly when people were leaving. Basenjis are curious and often will investigate purses, coats, etc. if given the chance. Theft of objects may occur.
Agree with Debra, you need to learn more about the breed. Behaviour with strangers is not a frequent complaint, but mischief and destructiveness are.....
