I used to read meters for a utility (P.G.&E.). Every time I was attacked by a dog, the asswipe owner of the dog would put their hands to their cheeks and say, "Oh my, he's never attacked anyone before". The response to that was, yes he's never attacked YOU before.
I remember I had a house on my route that had a yard full of Rottweilers. I was careful to make sure that the owner put the dogs in the house before I entered the yard. Even then you are weary, because if there is a kid in the house there is a 100% chance that he or she will wait until you are in no mans land and then open some sort of door so you can be eaten by the dogs for the childs entertainment. Anyway, one time I noticed blood on the street by the front fence. I asked the owner of the Rotts what happened, she told me that some kid was teasing her poor dogs and they got out somehow and attacked their tormentor.
She is a typical vicious dog owner, it's the victims fault, not her dogs and certainly not her fault. People with dogs that hurt and maim people need to serve some jail time.
