In the spring of 1942, the British started using, what they called “para pups”, with their first airborne army and SAS units. The para pups were trained to lead soldiers behind enemy lines, sniff out the enemy, and give silent warning and direction to the patrol.
One particular para pup, named Rob, was a mongrel black and white dog with a patch over one eye. He worked with the SAS. Rob would be parachuted in behind enemy lines, and would wait for his owner to find him and remove his parachute. Rob made a total of 12 jumps into enemy territory. He never failed to alert his handlers for the many months while they were behind enemy lines in both North Africa and later in Italy.
