We adopted a 1 yr old doberman a couple of weeks ago and also have a 6 yr. yorkie, my problem is that the dobie is still very young and wants the yorkie to play with her and i'm afraid she is to rough for the yorkie. The Yorkie also does not want to play. We cannot get the dobie to leave him alone. What can I do to train her to not bark and mess with the yorkie? I'm afraid she may hurt him playing to rough.
