Bella is just 13 months now and I can't really say that she is out of the puppy stage completely yet, so you probably have quite a long road ahead of you with puppy antics. As far as the chewing goes, that has pretty much stopped but she does shred her stuffies so I have stopped buying them. At least she realizes that her things are different from my things and my things shouldn't be chewed. Unfortunately you just have to be on top of your little one every minute, ready to scold or praise. It is just a matter of repetition, but fortunately over time it works. As for the biting, or puppy nibbles as we used to call them, we always said a loud "no bite" and then removed whatever human body part she was gnawing on from her grasp and stopped giving her any attention when she did that. Eventually she learned that we were more likely to play with her when she was well behaved. Again, it's just a matter of time, but she will catch on. Now if I could just stop her from occasionally stealing trash out of the small trash can in the bathroom!!
