I flew northwest, I did not get one and noone stopped and asked me anything. I hear they COULD have officials at the airport that COULD take your dogs into quarantine, but I dunno how true that is. I flew to and from small airports, maybe larger ones would have that, although I did lay over in O'Hare and nothing happened there either.
