'Emotional Support Duck'

From a New York Times article entitled "Wagging the Dog, and a Finger," on the rise of "emotional support animals," which so far require no formal training and minimal certification:

These days people rely on a veritable Noah's Ark of support animals. Tami McLallen, a spokeswoman for American Airlines, said that although dogs are the most common service animals taken onto planes, the airline has had to accommodate monkeys, miniature horses, cats and even an emotional support duck. "Its owner dressed it up in clothes," she recalled.

There have also been at least two instances (on American and Delta) in which airlines have been presented with emotional support goats. Ms. McLallen said the airline flies service animals every day; all owners need to do is show up with a letter from a mental health professional and the animal can fly free in the cabin.
