it's always an unsocialized dog allowed to run free. I don't know if you can ban a specific breed or would want to. At the end of the day, any dog can be dangerous. Fortunately, most are not. The point I was trying to make is 'turn the other cheek' only leaves you bitten on two cheeks. A dog allowed to bite and not totally contained will often bite again. The responsibility is with the owner, and consequences are the thing that will force his hand. The owner of the dog that bit me faced no consequences when his dog bit me. He was my sons friend and I felt unsure about 'being a jerk' about it. And the dog bit someone else, with much greater injury. My sons friend could have been forced with a semi-sympathetic person forcing him to confront his dogs ownership. Instead, he faced a justifiably angry victim who sued and won big damages, to pay for the losses she faced when the dog mauled her.
I suggest you force the owner to make you whole for your losses, and insist the dog be destroyed. Irresponsible owners permit these events to happen. Even if you collect nothing, by getting the dog destroyed will lower your communities risk that much.
