Two,Two I have one here and one on my business computer.
And no the pit bull owners who ARE responsible,have their dogs trained.Do their homework,find out about the dogs parents,dispositions,health problems,temperment,and can afford to take care of their animals do not have bad animals.BUT,people like the ones that have these two pits and their "witness"neighbors that have FIVE others within reach just make the responsible owners have to take flack.
