non-pet STR has dog, smoking inside

[Huiping S.]

The guests disconnected wifi, so we contacted guests for it and no response. Wifi connected to almost all system, including sprinkle, pool, Ring, Minute, AC, door sensor... So we came and found: dog eating things, dog toy on living room floor. 

For smoking inside, this property will fine minimum $500. How much to charge for smoking inside with evidence?

How much to charge guests hind dog inside in a non-pet STR?

If guests booked for 4 people but more than 4 lived there, how to deal with it? The STR can live 8 people. This is not first time found guests bring others, local relatives and lived there after checked in.

Thanks to sharing.
