Minimizing the Risks of Illegitimate Service Animals

Recently, I was in a restaurant enjoying a meal when a lady walked in holding a purse that had a little Shih Tzu dog wearing a tiny red vest with the words “service dog.” The dog was looking at a handsome German Shepherd seated near his owner at an adjacent table.  I noticed the German Shepherd was also wearing a vest, but this one was embroidered with “Emotional Support Dog.”  Then a cat enters the picture.
