I'm really glad to see this update, after being the victim like many of you of a person last year who was bringing a pet to my no-pets listing, and threatening me if I refused, by claiming it was an emotional support dog. She knew her rights, told me I could not ask what the dog is trained for, threatened me of discrimination if I refused, etc.. I think the "emotional support" thing was exploding and glad Airbnb took this action!
For all of you worrying about how to determine if the support dog is real: first now you are allowed to *ask* what the dog is trained to do, before you could not even ask!
And the new rules are clear, the dog must be under control (as such, obey basic commands). Service dogs will have absolutely no problem displaying that they are trained and under complete control! Most people with "fake" support dogs will however have a hard time showing that their dog obeys: come, sit, lie, heel, stay, and whatever service the dog has been trained to do. My rules now say that the guest must demonstrate on arrival these basic commands to ensure the dog will not endanger the neighbors or the community, and I am sure that anyone trying to bring a pet by claiming it's a support dog, will have trouble demonstrating these things.
