Thanks for all of your replies. That is pretty much what I do. I am just as persistent about it as she is. I will usually end up redirecting her, and win out.
There is an update to this situation tho. When she has gets on one of her tantrums where she is just trying to bite me. She will ignore her toys and everything, and just come at me. I have been grabbing her by the scruff, telling her no, and she will eventually get the point. Over the past two days when she has done this and I start to grab her, instead of acting submissive and whining like usual, it seems like it is pissing her off. I kept grabbing her over and over, because she kept coming at me, and finally she jumped back, lowered her head, and gave me a mean growl. It didnt seem like she was playing anymore, it seemed different. Is this normal? what should I do?
