How does the TSA dog expedite the screening process?

Upvote:1

Generally, a handler will walk with the dog along a line of luggage or passengers. The dog will 'alert' if it smells something it's be trained to notice like chemicals used in explosives or food. An alert can be a bark or the dog sits down, something like that.

I've seen dogs working at baggage claim and at lines for security screening.
