Hi,
I have a 5 month old German Shephard. She has been to obedience training but still has a big problem with biting me. She really hurts sometimes and the trainer has told me to pop her under her chin when she does this. There are times that when she does bite she does it where sometimes it is so fast and it hurst that I just react and smack her nose. I feel like all I do is pop her for biting. I am trying the technique of squealing or using ahhhh, it seemed to work the first day and today she is at it again. I had her fixed a week ago so I wonder if it might be hormone related as well. If someone could help I would be grateful. I try to love on her and all she does is bite it really hard to be affectionate to her when your afraid of the biting.
