None of my Basenjis have shown herding instinct, but to be fair they haven't had a lot of opportunity. Perry is interested in the horses and loves to greet them (and steal their carrots, if he can!), but they are a little big for a small dog. They were even a challenge to my Border Collie, but when all else failed he would get them moving by a nip at their noses. He was well aware the back end was dangerous! I have a picture in my mind (didn't have the camera with me) of him flying through the air snapping at my gelding's nose when the horse had been ignoring him…..
On the subject of temperament, and my recollection that my earlier dogs were if anything better than today's........I had lunch with my niece today and asked her if she had the same memory as I did of my earlier Basenjis. She remembers a very tolerant Lady, who put up with a great deal from her and her sister when they were young. This was back in the seventies. There was never any worry that Lady would bite a child. When the kids were young she put up with everything, including physical abuse, without a murmur. (I once caught the two sisters fighting over the dog, each pulling on the opposite end, literally trying to pull her apart!) When they were older and they got out of line, she would warn them, but it never went further than that. Never a problem with adult guests either, although she would help herself to their beverages if they weren't looking. 🙂
