Using a sense of smell 600 times greater than a human's, the Miami dogs have scored some remarkable victories over drug smugglers. In one spectacular seizure last year, which isn't documented on Nabisco's cards, Iowa alerted his handler to a shipping container passing through the Port of Miami. Customs officials discovered about 41,000 pounds of cocaine concealed in that container and fifteen other sister containers. Iowa was credited with the entire haul and now boasts $2,314,090,865 in total career seizures, a national high. Not bad for a mongrel who, like many other Customs dogs, nearly ended up on the wrong end of a syringe at a humane society.
