I don't have 3 yorkies....yet. But I do have 4 dogs, a maltese, a yorkie, a yorkiepoo, and a cocker. And I will be getting another maltese and another yorkie within the next couple of months. The only time it is really a mad house is when someone comes over or is at the door, but even that only last 5 minutes. They all get along and behave really well all other times. So for us, it is not a mad house at all. I love having this many, it would be very lonely and seem bare without that many.
