It is the alpha dog’s right to control the movement of the dogs under him or her. Alki takes this very seriously, and either to frustrate him, or just to make sure he still knows who’s boss, she will block the doorway, hallway, etc, and refuse to move to let Chester pass. This results in his sitting and crying about it until we make her move. He would probably just sit there and cry and pee on the floor if we didn’t intervene. He certainly does not have the authority to pull rank and step over her – she’d put him DOWN if he tried. Here she lounges across the hallway, trapping him in the office until his whining annoyed us enough to step in.
