Covered.Too lazy to read ALL of the posts so apologies if this is already determined; you said the parents were aware of the aggressive nature of the dog, were you? If so then you bear some responsibility. . .
Obviously I'm not trying to win any popularity contests this morning.
I guess I can't keep from asking - how do you know "the parents were aware of the aggressive nature of the dog." If after the incident did the parents tell you they were aware ? From your description of them they don't sound like the kind of folks that would volunteer that kind of information.
I would think if there is an indication the animal was vicious and subsequently allowed this to occur they could possibly be charged with a criminal offense (?)
The daughter who is In my daughter's class at school had told my kids they couldn't go inside the house because they have a dog who bite's. I was only told this by my kids after the fact. I didn't even know they had a dog before this happened. I would have never allowed them over there had I known.
