The Border Patrol Had Four Legs

A 1901 collection recounts dogs carrying contraband across Netherlands frontiers before 1795. One dog travelled ahead of the laden animals. If it scented customs officers, it turned back, signalling the others to retreat. At the receiver’s house, the scout went first again; a whistle meant the others could approach with their goods. The dogs carried the contraband, but people supplied the cargo and destination: behind the animal operation was human smuggling.
