In the latest (10/20/14) New Yorker, a hilarious and simultaneously disturbing piece by Patricia Marx, “Pets Allowed: Why are so many animals now in places where they shouldn’t be?” (starting on p. 36), about emotional-support animals. From p. 37, on E.S.A.s vs. service dogs:
Contrary to what many business managers think, having an emotional-support card merely means that one’s pet is registered in a database of animals whose owners have paid anywhere from seventy to two hundred dollars to one of several organizations, none of which are recognized by the government. (You could register a Beanie Baby, as long as you send a check.) Even with a card, it is against the law and a violation of the city’s health code to take an animal into a restaurant. Nor does an emotional-support card entitle you to bring your pet into a hotel, store, taxi, train, or park.
No such restrictions apply to service dogs, which, like Secret Service agents and Betty White, are allowed to go anywhere. In contrast to an emotional-support animal (E.S.A.), a service dog is trained to perform specific tasks, such as pulling a wheelchair and responding to seizures. The I.R.S. classifies these dogs as a deductible medical expense, whereas an emotional-support animal is more like a blankie.
In the piece, Marx attempts (sometimes successfully, sometimes not) to take (purported) E.S.A.s into places where animals are in fact not allowed, using creatures borrowed from acquaintances: a turtle, a (large) snake, a turkey, an alpaca, and a pig.
