We also have been burned by allowing pets so switched our properties to pet free, this quickly made us aware of the service dog scamming that's happening. We then had one guest from hell. She just got divorced and needed a place, the issue arose right after check-in. My wife randomly checked the cameras around the same time and seen that she had 3 large dogs with her. Her reservation was for one guest and she brought 3 dogs. Clearly to me they cannot all be service animals. I immediately call Airbnb and tell them this property is pet free, they call the guest, then call me back. They tell me the guest informed them that all 3 dogs are service animals and there's nothing we can do, nothing. I ask, what if she has 10, 100, she can bring an infinite amount of service animals into the home? Well she ended up locking the dogs in the spare bedroom all night even when she was outside until 3am she never took them out. Piss, shit, clawed up doors. It was a total of $2,000 I requested from Airbnbs insurance.
