I agree. My Bebe was like that when I put her in her playpen. She would cry until someone notices her. So I heard that if you totally ignore them, they will eventually get the hint that they won't get their way. Hahaha.. I would put her in her playpen and not even look her way. She would start barking, then it went to a wimper, then a purrr... and eventually she would stop and klonk out. Hehehee... It really works. Make sure u don't look at your puppy, because they will know.
