OK, I just had another thought. I would report this sooner than later. Let's turn the table around. What will happen if the police knock on your door and tell you there is a complaint against you for assaulting this guys dog ? He is in the wrong and I think the police would see right through his story but just saying.
Also, in my case, with warmer weather coming, if I heard someone was bit later this year, I would feel I should have said something, but that's me.
Tell the police ALL of your concerns! If you know this person(s) as bonkers, let them know that. They will appropriately let them know what they wise thing to do is. No harm done, your not starting a war, just nipping it in the butt. Yes, there was pun intended.
