It's the only reason why I probably won't own a stafford again. My own stafford is not DR/DA at all... having said that I have no doubt that she may not instigate a scrap, but she would certainly participate. Her tolerance is very high with dogs she knows, but I have seen other strange dogs pick a fight and her reaction said a lot. But funnily enough, having my own Chi x being DA made me realise that I would like to not have a DA dog next time. I would like to compete in sports and not have to micromanage every walk lol. Getting a Stafford (as much as I adore them) may just be asking for heart break. Maybe it will be less of an issue later in my life. Right now I just don't particularly want to deal with it again.
