Mouthy at 6mos..
I just spayed my female gsd. She just turned 6mos. Had her since 2mos. She is still using her mouth on my hand when she doesn't want me to do anything. Not that I stop doing what I was doing. I've tried the loud No, holding her lips around her teeth, using my thumb on her bottom jaw, trying to get her to stop and show her I'm not afraid of her mouth. Any suggestions? We also have periodic challenges with her front paws. I've raised and trained collies but she is 65pounds and seems to have domineering tendendcies..
