Most of the JRTs that I fostered had bit people. But is was deemed due to stupid human error and not 'aggressive dog' I don't know. I know they did before. Maybe not when you were doing it, but before that?
Many JRTs that are coming in have bit people. Most are non puncture type 'bites' The one that I had to fight to have put down..had mangled the guys hand. (and was really quite a scary dog in many many ways...though I got along with him) I guess the law suit thing isn't as relevant anymore as insurance companies (and lawyers) are realizing that ANY dog can bite. And that people lie.
