You've heard of therapy dogs, but at San Francisco International Airport there's a new addition to the four legged animal therapy team.

FOX's Jim MacKay has the details:

Who says pigs can be helpful in therapy? The animal assisted therapy program at the San Francisco SPCA just certified LiLou. She's a big that will be greeting passengers and helping people calm down that are afraid of flying at San Francisco international.

LiLou was just introduced as the first non-dog therapy animal in their program. So far so good. Officials at the airport saying she's fitting in just fine and gets along with everyone.

LiLou will be making an appearance at the airport at least once a month.
