My poor dog is getting confused with this not meeting people. She can hear my son when he knocks with a bit of shopping for me. He stands on the pavement and has a chat. The dog can hear him and is standing on her hind legs trying to see him over the half door. I come back in and she expects him to be with me and is disappointed when he don't come in. Same when he brings the kids with him, she can hear them and gets so excited and want to see them. I wonder whats going on in her mind.
