A 9-year-old black Labrador retriever named Argo is gearing up for a busy holiday travel season. Argo is trained to detect potential explosives at Baltimore-Washington International Airport and is one of 12 dogs featured in a 2025 TSA canine calendar. During a recent demonstration of his skills, Argo was presented with a decoy person wearing a backpack containing something that smelled like potential explosives. He immediately reacted to the scent by dropping his nose to the ground, wagging his tail faster and pulling his handler toward the target. Explosive detection dogs are trained at the National TSA Canine Training Center in San Antonio, where Argo was assigned to Lilly.
