    LOS ANGELES, CA (CNN) -- Los Angeles International Airport is going to the dogs, literally.

    This week, LAX launched a new program called "Pets Unstressing Passengers," or "PUP" for short.

    Have you seen some of the canines wandering around the airport? The goal is to have the dogs ease tense travelers as they wait for flights.

    Research shows pet therapy helps relax people, decrease blood pressure and heart rate.

    Officials hope these dogs help improve the atmosphere inside the airport.

    In 2012, Travel Magazine named LAX the second-worst airport for patient satisfaction.
