A passenger settles into his seat, next to the window on a plane… when another man sits down next to him, and seats his Black Labrador Retriever in-between them.

The first man looks very quizzically at the dog, and asks why he’s allowed on the plane. The second man explains that he’s an undercover police sniffing dog. His name is Sniffer, and he’s the best there is.

I’ll show you once we get airborne, when I put him to work,” said the second man. The plane takes off, and once it has leveled out, the agent says, “Watch this… ” He tells Sniffer to ‘search’ . Sniffer jumps down, walks along the aisle, and finally sits very purposefully next to a woman for several seconds. Sniffer then returns to its seat and puts one paw on the agent’s arm.
