I don't think any breed is bad. You get out of your babies, what you put in to them. If you don't train & work with your puppies they have no idea how to act. If you leave them outside all day with nothing to do. What can one expect.
Rotti's are called dangerous too. Well I have one who thinks she's a Yorkie. She wants to sit on your lap, just like Princess. So like I said, it's what you put in to them.
