Being a zookeeper and the amount of animal 'training' involved, I enjoyed the discussion on operant conditioning in episode #110 (Sorry I know I am behind on episodes again, I'm catching up now.) Now be sure you use your bridge, in this case the clicker was discussed, at the correct time. If you use it at the incorrect time you may link an incorrect behavior from your Chris. Be sure that you are consistent as you mentioned and do not send the incorrect signals to your Chris. If you need assistance training your Chris just let me know. I may have advice on the matter.
