At Los Angeles Airport Provided Therapy Dog.

Not a fake dog, dogs airport invited to tour not to search for drugs or explosives. They combed the people who need a friend, for the belly rub or massage the feet for light.

"His job is to be touched," said volunteer Kyra Hubis about Henry James, the golden retriever breed five-year-old who works a few hours a week at the San Jose Airport.

"I just stood there with her​​. They talk to him. If I had to answer him, I do," he said as quoted from nydaily.

Mineta San Jose International Airport was the first to introduce therapy dogs in the days following the events of 11 September 2011 When the flight was canceled and passengers stranded by many who become anxious and afraid.

These dogs are meant to handle the stress experienced by the passengers.

"You can really feel the stress begin to decline, people began to smile, strangers start talking to each other and everyone is running really well," said the director of volunteers at LAX, Huebner.

The therapist's dog had to be healthy, skilled, stable, polite, said Billie Smith, executive director of the Wyoming-based Therapy Dogs.

They should feel comfortable with the crowd, sounds, smells - and they also have to pass through the security process as all airport workers.
