I feel like heading to Lansford PA and smashing said neighbor into tiny quivering shreds.
Not that I believe you are seriously considering that, as understandable as it is, I would strenuously advise against it. It's a path that leads to nowhere but destruction. Pray for the neighbor too, trust me it works!
PA has a law on the books where if a dog bites three people, it gets destroyed.
Small consolation.
