I have 2 toy senior toy poodles, 2 yorkies and 1 biewer girl and I have to say my biewer girl barks or whines more than the other 4. She is also a little more clingy. I agree with the description of the yorkies acting like they are on patrol. That is definitely what mine do. My biewer will do the patrol thing, but loses interest in it quickly and then comes to sit by my feet or in my lap. It might just be personality differences but my biewer just likes a little more attention then the other dogs and the little clown knows how to get it too. She is still young so maybe it is that she hasn't finished training me yet, lol.
