Clicker trained dogs will learn a repertoire of behavior they try out in training sessions, just by shaping a lot. So notice in the ottoman shaping video, how Bell immediately knows to interact with the object on ground and knows to try her nose, mouth and pretty quickly here her feet. If you are beginning--your dogs will not yet have a big repertoire--but will get one fast if you do lots of shaping. Notice too in both videos how Bell seems to "forget" what is getting clicked part way through for a bit--very typical. Also notice how short my sessions are and notice how I have her attention the whole time. That comes from always working with you dog while she is "in the game" (see slides posted below and manual). Notice too--even with lots of exprience any one of my session is very very short--yours should be too. Short and total attention.
