There are quite a number of posts about when is it best to go for compensation for damages caused by poor guest behavior. Considerations: you must contact the guest first to alert to damages and cost. Guest is alerted to your claim and usually responds defensively. You file a claim providing proof that specific guest caused the problem. As to getting the money for the pet, you can request it, but getting it is another problem. While you cannot get file a claim for rule breaking, you can provide a very negative review. Of course you will more than likely get a negative review as well. Never a good place to find yourself. Perhaps the only thing you can really do is learn about how to avoid or mitigate such situations. Any thoughts about how you might do that?
