Airline passengers have to deal with a lot these days; getting bumped from flights and losing luggage on top of the general anxiety that nervous flyers always feel.

At the Cincinnati Northern Kentucky International Airport, miniature horses deliver a calming force two times a month. Denver and Ruby, two of 34 therapy horses at Seven Oaks Farm in southwest Ohio, trot out of their trailer and into the ticketing area.

That’s where Shoma Anjola spots them. He’s traveling from Toronto and saw a therapy dog at another airport. “It’s quite amazing that I saw one on my way and then one [on the way] back to Canada. I’ve never seen any in my entire time traveling around different airports.”

During Kentucky Derby season, therapy horses dress the part as they greet passengers at the Cincinnati Northern Kentucky International Airport. More than 30 airports across the country now have therapy dogs. San Francisco has a therapy pig. San Jose, Calif., began a dog program after the Sept. 11 attacks and now has 21 therapy dogs and a therapy cat. To read more from ANN THOMPSON, click here.
