options there are a couple of avenues to explore. First if you live in the city or county. Go back to the police. Tell them you want to know if there are any ordinances or statutes under which either you or they can press or sign charges. Either they as an entity or you as a citizen. Do not let them blow you off on this. Most venues have ordinances that cover items that state statutes don't cover. Example: in our venue, noise complaints of barking dogs.. neighbors get fed up, call, cops arrive, dogs are quiet, cops can't prosecute because they didn't observe/witness it, so the neighbors have and exercise the right to sign a complaint and the neighbors are prosecuted and fined based on that complaint. If they can't/won't sign a complaint, you may be able to exercise your rights and sign. If you can get anything pushed through criminally on this in your favor then it becomes a win win, because a win criminally is pretty much an automatic win in a civil when you go for the monetary. There should be some ordinance violation here of some sort of failure to control their animal and causing damage to property. Whoever suggested going after their landlord was also correct. Also, be sure when you go to the police to obtain all copies of the incidents and officer's responses, any paperwork, reports etc... that was generated by this call.
I cannot imagine what you are going through, how horrifying. My heart would be screaming for some sort of primal eye for an eye scenario. In our society hitting their wallet and attempting a successful run a getting them out of the neighborhood is about as close as your going to get.
