Candy isn't very good at listening yet so I just put her away when someone comes to the door. For Visa, I put her in a downstay until she stops barking. Then I allow her to come greet the person. Back when Visa was shy, this really helped improve her. When she's in a downstay away from the door, she can't see and becomes curious and excited as to who is there, rather than suspicious. She isn't at all shy anymore but I still continue to do it because I find it helps quiet her.

To me, it is unnacceptable for dogs to jump around barking at someone at the door. I always had dogs that did this growing up and it annoys me to no end to see it happen now. Candy still isn't very well trained since I just got her, but Visa has been taught with quite strict rules and she knows not to be rude. I wonder how effective training will be when I have four or five dogs though lol. Probably not great.
