I can't get Charlie to stop nipping at the kids! All and all, he is very calm and well behaved, but EVERY time he gets excited, and starts running with the kids, he will nip at their hands, and cloths. He never jumps up on them, so we don't have a problem with him knocking them down or anything, and he only nips when he's running around with them. I correct him when I see it, but more often then not, I don't see it, someone just comes running up "Charlie bit me!" He's almost 4months old, will he just grow out of this? I've tried running around with him myself, to see if he'll nip at me, so that I can correct him then, but he won't do it to me or my husband. He's the most intelligent dog I've ever owned, already he knows sit, stay, down, paws up, shake, and roll over, and he's getting pretty good at jumping through Abby's hula hoop. So I know it's not that he doesn't understand that we don't want him doing this. He just wont stop, and its driving me nuts. He has ripped a few pairs of shorts, but he hasn't broken skin yet. Any advice?
