Before she was spayed she was obviously the alpha dog. She would take the bones and toys away from him and pile them up in a corner but she never growled at him. She is out of hand now. They do not even play with each other anymore. With me and my boyfriend she tries to boss us around but we do not let her. For instance she will bring us a ball and place it on our lap to play. If we do not pay attention to her she will keep nudging it to get our attention. If we say no, she will bring it back. Eventually she gives up. I saw an episode of the dog whisperer and he said not to play with them when they do that because they start seeing YOU as a toy to play with. I just do not know what I can do at this point to stop her from being so aggressive. Any suggestions?
