My previous males never had an opportunity to meet other basenjis (outside their breeder kennel) so don't know if the experience with my current female is "typical" or not. The first time she encountered another, it was a tri-color older female that was a real bitch and instantly got aggressive (now whenever they see each other its "hackles up"). The first time I took her to a lure coursing event, mine was friendly enough until a little blind female came up and bit her. The second time I took her to a LGRA event, a lady came up behind us (while mine was trying to potty) with her tricolor female and her dog attacked mine. So now hackles go up any time another female comes within shouting distance.
