Typically when you see a dog wearing an official-looking vest at an airport, you’re on high alert. You don’t run up to the dog requesting kisses. You don’t kneel before the animal and say, “WHO’S A WIDDLE BOY?” You don’t scratch the dog in that “sweet spot” near the tail, right there in front of TCBY.
Well, you still don’t want to do those things to an airport security dog, because you might be arrested. But you do want to do those things to the therapy dogs patrolling LAX, because that’s their job.
