Travelers flying in and out of San Francisco International Airport are in for a treat: Not only does SFO have an animal-therapy group, the Wag Brigade, but it’s just hired its first non-dog member: LiLou, a dancing, toy-piano-playing, tutu-wearing Juliana pig.

“It was like an A-list celebrity walking through the terminal,” says SFO public information officer Doug Yakel of LiLou’s Monday debut. “You couldn’t get 10 feet without people running up to see her or taking out their cellphones to get a picture. She really has a magical effect on people.”

SFO, which launched the Wag Brigade with the ASPCA in 2013, joins several airports that have brought in therapy animals to help soothe anxious travelers. Los Angeles’ LAX has the Pets Unstressing Passengers (PUP) program, Denver International has the 53-strong Canine Airport Therapy Squad (CATS), and the Cincinnati/Northern Kentucky International Airport has Dakota, a miniature therapy horse.

“It’s a proven scientific fact that petting an animal lowers blood pressure, lowers the heart rate and slows breathing down,” says Nancy George-Michalson, executive director of New York Therapy Animals, which dispatches trained dogs to hospitals, schools and libraries.

She’s brought her own poodle, Melody, to perpetually snarled La Guardia Airport to help cheer up people waiting on long security lines. While the Port Authority doesn’t have a dedicated animal-therapy unit for travelers, George-Michalson believes one of the most visited cities in the world needs one:

“It’s definitely a nice respite for people who are traveling, especially during the holidays.”

Even if you aren’t flying out of SFO any time soon, you can see LiLou’s adventures and killer outfits on her Instagram, @lilou_sfpig.
