Absolutely! Whenever she is showing the behavior you want to discourage..this is the time to do it. Hold her down until you feel her body totally relax. Of course she will continue to test you..but it won't take long and she'll put two and two together. It's not so much the jumping up here..but the nipping and biting. It's a progression to aggression that you are trying to control! As you feel more in charge doing this, she will sense your confidence. Keep it up..don't let her bite..nip or growl at any member of YOUR pack..2 legs or 4!!
