I’m shattered emotionally....

Fortunately the bites were minor but the threat of a law suit and possible big bite damage is too much for me I would never be able to forgive my self if there was an even semi serious bite
Thats why you get ahead of this
Explain the dog is gone, pay for the bills and hope they forego the idea of lawsuit

If they find out you're a decent guy and not just "that jersey with the killer dog" you got a much better chance

Besides, lawsuits ruin neighborhoods
