• Denver International Airport is home to the world’s largest airport animal therapy program.
  • There are around 45 programs across US airports, with LAX being Denver’s biggest competitor.
  • Volunteer manager Karla Grahn told Insider the dogs were in demand during the summer travel chaos. 

In September, Denver International Airport took the Guinness World Record for the largest airport animal therapy program, snatching the title from LAX.

The program, which has been running for eight years, will appear in the 2023 version of the record book.

Take a look at some of the canines, and one cat, that roam Denver’s airport.
