Long overdue and ASKED FOR (repeatedly) by the flying public and those with actual *trained* service dogs. We have seen far too many entitled (aka spoiled) pet owners LIE thru their teeth – to get a pet animal (not just dogs, btw) on a flight with them, and such animals often display little to no training (including NOT being housebroken) and are NOT acclimated to remain calm on flights, and are often of very poor and/or dangerous temperaments, leading to actual BITES or physical injuries to other passengers or stewardesses. Absolutely NO PROOF of training, (or even good health) of said animals, has ever been required, before now.
