Therapy pig employed by airport wears a blue 'pet me' vest to calm down anxious flyers awaiting connections
Wagging her tail happily and spinning round for treats, this piggy in a tutu is here to make nervous air passengers feel better.
Little LiLou the pig has just joined the welcome brigade at San Francisco International Airport , and she's quickly become a favourite fixture.
The pig, who is a Juliana breed, is one of the special creatures who can help soothe customers who are concerned as they await connecting flights.
Animals like LiLou wear vests that read 'Pet Me!' so people know that they are there to help as part of the WAG Brigade.
Christopher Birch, the Director of Guest Experience, said: "Since its launch in 2013, the SFO Wag Brigade has become a favourite amenity among travellers.
"With the addition of LiLou, we can look forward to more moments of surprise and delight for guests at our airport."
San Francisco SPCA Animal Assisted Therapy Manager, Dr Jennifer Henley, said: "We have more than 300 dog, cat and rabbit volunteer teams, but LiLou is the first pig in our program.
"It's wonderful to witness the surprise and delight that LiLou brings to people during therapy visits.
Therapy dogs are already deployed at airports in San Francisco, Los Angeles, San Jose, Miami and Edmonton in Canada.
Earlier this year Daniel went viral after people saw the images of the emotional support DUCK supporting his owner onboard a flight.
Flying on board as a companion to Carla Fitzgerald, Daniel the duck was there to offer a calming influence when she had to catch a plane.
The duck was snapped by Mark Essig, who met the bird on a flight from Milwaukee to Charlotte, NC.
He tweeted: "[Daniel] is an Indian Runner (an Indonesian breed), a certified emotional support duck, four years old, wears a Captain America diaper."
And in January, Jodie Smalley flew with her 'emotional support' turkey, Easter, from her home in Seattle, Washington state, to her relatives' house in Salt Lake City, Utah
After the plane touched down, she lovingly pushed the feathered creature through the airport in a wheelchair, before taking it to her brother's house for festive celebrations .
Emotional support animals may be used by people with a range of physical, psychiatric, or intellectual issues. An animal does not need specific training to become an emotional support animal.
