Motorcycle u Cover Plane Suffering Subject

A beautiful good day desired. Here’s what everyone already knows! Motorcycle under a cover tarpaulin and standing in front of the door, (citizen’s gate) It doesn’t take long and there were already the first “piss tracks” to see! So now the question actually! The legal basis, can someone say something clever? If I see one pissing with his dog on my hood / motorcycle, is that property damage? I’m no animal enemy or anything else from now on I would like the H old with a big spade down! In the middle of the face! PS = hope is not wrong board MfG BTA
