sounds like you need to make her move when she does this to you.
Don’t allow her to come near you with her ears back and teeth bared. I would carry the rope so you can swat it at her and make her move her feet and continue to do so until she stands still, nicely, Ears forward, etc.
My horse tried to pull this with me when I would pick up his feet. It took about 30 minutes for him to catch on that it wasn’t acceptable.
