"I can see that she is happy showing off her tricks and getting her praise," LiLou's owner, Tatyana Danilova, told USA Today. "It also brings positive emotions to me seeing that we can do something good for the community and bring more smiles in some unconventional way."
LiLou visits the airport at least once a month, according to airport spokesman Doug Yakel, who also said that the airport has been working with the San Fransisco Society for the Prevention of Cruelty to Animals to expand the types of animals included on the Wag Brigade. Lilou, who will turn 2 on Dec. 15, is the first pig to be certified in the Animal Assisted Therapy Program of the San Francisco SPCA.
The SFSPCA requires that "At a minimum, AAT pets must be solicitous and fully comfortable with handling. In other words, pets must be interested in and eager to approach people and accept handling, regardless of the person's age, gender, race, size, mobility equipment usage and apparel."
According to Conde Nast Traveler, more than 30 airports nationwide have programs that feature therapy dogs, and the Cincinnati/Northern Kentucky International Airport has brought in miniature horses in a similar effort.
