Emotional support animals have been in the news quite a bit during the last couple of years. There have been reports of airline passengers boarding with a peacock, hamster, pig, a duck wearing a diaper and a squirrel. As a result, companies have started to change their policies, and the public’s attitudes and perceptions toward ESAs also appear to be changing.

Frontier Airlines recently announced its new policy to allow only cats and dogs as emotional support animals. It joined Spirit Airlines, Delta Air Lines, United Airlines and American Airlines, which have all tightened their policies on ESAs this year. Publix also banned them from its stores and posted signs reading: “For food safety reasons, only service animals that are specifically trained to aid a person with disabilities are permitted within the store.”
