@eeeefarm Good points. My own experience... When I went to Medfly (Karen's) to look at Basenjis I had my wife and son with me. Karen would bring out a dog and I would size them up. Would they look at me, would the come up to me, acknowledge me, kiss me, etc. I was looking for aggression.
When she brought Jengo out the second time, I loved what I was seeing, so I asked my son (maybe 9 at the time) to run across the yard. I wanted to see if Jengo would run, show aggression... didn't actually know.
Jengo ran with him, but never chased, jumped or nipped. EXACTLY what I was looking for. They ended up at a chain link fence with their backs to me looking at a horse in a pasture. I placed my hand on Jengo's back right up against his tail ready to recoil fast. He glanced back and went back to the horse. That's the second I knew I was screwed. I didn't want a Basenji, but this one was perfect. The rest is history.
Most of the time if I run with mine in the backyard, they just look at me like "What are you doing, Monkey?" They sit there. I've just not had to deal with a chasing issue. Except for squirrels, goats, and dogs. Mostly squirrels.
I miss my Aussie/Border Collie mix.
