I just wanted to post an update on our nipping issue with Dexi as I appreciate all the helpful info that everyone gives. We have hired a trainer, not only for nipping issues but just general obedience. She is certified and has basenji experience from working in NYC. On another note our girl seems to be listening better and not nipping as much, and I don't allow chasing games with my son. We had a big crowd for Easter and she loved it. So friendly to everyone, adults and kids, well behaved too. She knows her name and listens to commands come Dexi and sit. We are working on stay.
That sounds very positive. I think you are on the right track! 
Improvements are happening. Good for you guys for putting in the work!
Awesome. I'm glad to hear things are getting better.
Good for you! Things will continue to progress if you keep being gentle but firm with her. Once you son and the puppy learn the rules it sounds like it will be a wonderful match.
I agree. She is such a friendly little gal.
