You got this. Pay attention to Cesar Milan my friend. He taught me everything I know. He goes to the most extreme and can make change in any dog. If not he admits it and explains why. Most of the time he is having to train the owner. They are the problem 99.9% of the time. Not you... you dog is not a puppy. So... get my context.
Calm assertive energy. No question what needs to be done. The dog needs to know YOU are in control. But you have to be consistent and calm. You can't be mean. You can't get angry. It will make her anxiety she has come out. She needs to know she is to trust you. It works with people as well. We are much the same.
