We once had a dog that was in the bedroom barking and then would come into the living room and look all around acting kind of confused. Then would run back into the bedroom again and start barking only to return to the living room and start the process over again. Finally I went to the bedroom to watch him and he was barking at the full length mirror that was there then run to the l/r to try and find that other dog that was on the other side of what he apparently thought was a window.
