Sorry, I didn't mean to state good dog--bad dog.  It was that these three dogs were in the right spot at the right time.  And I'm thankful.  It just happened that they were pits.  I agree with all those that stated other dogs would have handled it differently. But, once the bear was dead the dogs just left and I have no idea to where or where they came from.  Like I said, no one within five miles of where I live owns a pit bull.
If I ever see them again, you can bet I will feed them, might even give them a beer if they want one.  Agian, I am not a pit bull person, these dogs just were.  Had it been a jacck russel or a great dane, I would feel the same way towards them.
