Haha, there definitely is not!
I work part time at a kennel/boarding facility and adore each yorkie I have met. They're the one breed who is always so sweet and full of personality. They all have their own ways of behaving and I love them all. I was never a small dog person until I got Rhia, my yorkie. Even after four years together she still surprises me with her little quirks and new things.
