Thanks for all the tips and support. I found some more information on clicker training that explains things way better than this instructor did so I have decided to dump the class and I really am so much happier (I didn't realize how much my frustration with the instructor was affecting me:().
We did learn a few things in that class and with the tips you all have given I think Gossy is progressing well. The other day I was practising using my hand as a target stick and it ended up she healed without the leash! She did the same thing last night and for a significant distance. I was impressed! Of course now we need to work outside with more distractions.
Happy days are here again :).
