[QUOTE=kam2490;3985191]Also, how do you encourage calm play when they're running around and biting?[/QUOTE
I just refused to play with Gracie when she was acting all crazy. It was touch and go when she was a little one. I could not even touch her when she was crazy. When she was acting normal I would work a little with her on her sit and stay. I would put her harness on her only when I was waking her from a nap. She learned not to fight the harness because she learned the harness meant she was going out and she loved that.
Teresa Ford has some good techniques in dealing with biting. With a young one you really have to keep them as calm as possible and refuse to play with them when they are acting up.
I have to say that when I saw my little puppy, Gracie, roll on her back and show me her teeth and growl I didn't know if I should laugh or be afraid!
I had never had to deal with something like that. She is really a sweetheart now.
