one of my friends has a couple of pits. I went over and fed them/checked their water/gave them treats one time when she was out of town. I had been there before that weekend so they would recognize me, but I was still nervous because of their reputation as being vicious dogs. They were as wary of me as I was of them and I did NOT stay very long but they were fine while I was there other than being wary of me.

I am cat person, maybe they sensed that.
