When I was researching for a dog and I fell in love with the yorkie... they said that they were always acting like the big dog around HUGE dogs. This was such a turndown for me(even though i couldnt imagine another baby for me). But, Bailey is the exact opposite. When ever she sees a dog on a walk when she goes to say hello, she rolls over on her back so the dogs can smell her! I think this is so funny, and everybody starts to laugh when she does this. Haha! Is your yorkie submissive or not?
