I don't have any advice, just read the thread and have a similar problem. Gracie is 4 and half months and she has just begun to show her defiance. She won't come most of the time and when she does she just gets close enough to not be able to catch her. She thinks EVERYTHING is a game..and when I fold clothes she takes off with a piece and runs behind furniture wanting you to chase her. I am going to look for the book recommended...I dont know much about clicker training, maybe I should look into that too
