I have heard that you should make your dog sit and wait, after the door bell has rung or the knock on the door happens and she starts getting excited make her sit or lay down and tell her to wait. Then you go to the door and greet your guest, BUT if she gets up to follow you to the door do not open it, make her sit/lay and start over. It may take a while, and you may want to warn your guest that it could take a while, but once she stays, and you welcome in your guest, tell her to greet and hopefully she won’t jump up!! If she does jump start ALL over again!! It can take time so get a friend who understands and is willing to help!
