@tanza:
Keep in mind that many years ago Basenjis did NOT have the best of temperaments.
I hear this all the time, but it just doesn't match my experience. I had my first girl over 40 years ago, and she had the best temperament of any Basenji I have ever seen (and better than most dogs I have seen). She was great with people, especially children, and fine with other dogs. No problem at the vet's, and my Mom took her along at Tag Day for the humane society, where total strangers grabbed at her and picked her up, resulting in a very loud yodel and nothing else.
My second Basenji I got in 1975, and she was also extremely tolerant of children, indifferent to strangers, but same sex aggressive. At the time I visited a number of breeders before I got her, and none (zero!!) of the dogs I saw had bad temperaments, and I saw and interacted with quite a few, including handling their pups. The males were pretty laid back, and the breeder I got my third Basenji from seven years later had multiple dogs of both sexes running together (although she did run 2 packs). Again, none were aggressive with people.
My current Basenji is the only one I have worried about with strangers. His attitude has gotten worse since my husband has been unwell. Perry doesn't like people (nurses) who arrive and cause his person pain, and I can no longer trust him with new people, but I think that is pretty understandable.
