LINTHICUM, Md. (AP) — When Argo walks through the doors of Baltimore-Washington International Thurgood Marshall Airport, he knows it’s time to work.
The 9-year-old black Labrador retriever spends most of his waking hours patrolling the airport, with his sensitive nose finely tuned to detect potential explosives.
He sidles up behind passengers and gives them a good sniff. If he gets a whiff of anything suspicious, he immediately alerts his handler, transportation security specialist Jonathan Lilly.
