Mitzi needs a "key - word" like "stay and be good". Whenever we have to leave her she goes in her play pen with water and her dolls. If we forget to tell her the "key - word" she barks and whines. Even when my husband goes to work and forgets to tell her to "stay and be good" she is looking for him all day long all over the house even though I'm always there. She is totally "Daddies little girl".
