You need to check out Emily's law, which Meemaw recently signed. I don't know if it is state laww or was just a local Ordinance in Selma, but even there, where we were often behind the times, a dog that bites someone was picked up and held for observation at either the Shelter or a vet for 10 days at the owner's expense. We also had a Vicious Dog law that had the owner responsible if there had been previous signs of aggression.

At minimum, their homeowner's insurance will cover the cost of treatment, etc. and jack the owner for it.
