No.

There are a myriad of personality traits that I would advise a beginner to watch out for, as well as to look for some breeds that *tend* to be quieter and smoother, but on the whole it's a case by case thing. It's all about how well the horse is trained and how willing they are to put up with beginner mistakes.

I learned to ride on two lovely old Arabs (as well as TBs, QHs, a couple mustangs and a paint), and there was nothing crazy or dangerous about them.
