Regrettably we seem to be living in a dog loving world where dogs are being given more and more freedom. They can be a big problem in campgrounds or really anywhere. Usually the owners are conscious of other people's rights but not always. In this case it was a very dangerous problem. I would sue and seek to have the owner arrested for contributing to the attack. I enjoy a small well controlled dog but we need to stand up to dog problems and owners or it's going to get worse.
