I'm glad to see that (as far as I can tell) this isn't directed at one particular breed of dog. One of my dogs is a pit bull - a breed that I was previously terrified of, but this dog was dumped on me. He was a puppy and we've been to obedience classes. He's a little over a year old now and the sweetest, most laid back, well behaved dog. To be honest I still wouldn't be comfortable around a pit I did not know, but that's true of most big/very strong dogs.
I do hate though to see pit bull's targeted in these type of laws (which doesn't seem to be the case in this law). I have another dog a small yorkie-terrier mix that is very prone to snapping. He could never be left with a child. Of course the difference between him biting and the pit biting is a minor owie and possible death, but I still think owners of all sizes of dogs need to be more aware and held responsible.
Too often little dogs are excused for being snappy because in most case their bite doesn't do much damage. But a bite from a small dog can get infected, scar, or make a child afraid of dogs. I hope more places that institute Dangerous Dog Laws include all dogs in their laws.
