 But what's the definition of vicious anyway? Vicious might have its own legal definition. But it seems to me that the definition of vicious or dangerous is purely subjective, right? I mean, what I think is a vicious dog might be different than what you think is a vicious dog and different than the person who was attacked by a dog when she was a child thinks is a vicious dog. In addition, maybe that dog's only dangerous in a given situation or environment or around certain kinds of people.
