As the dog sniffs her way toward record cocaine interdictions, she has become the latest target of Colombia’s most powerful drug gang. Colombian police recently revealed that the Gulf Clan, a cartel that boasts its own guerrilla army, has offered a reward of $7,000 to whoever kills or captures the savvy hound. The threat prompted officials to relocate Sombra  whose name in Spanish means Shadow from a busy port on Colombia’s Caribbean coast to the capital city, where she now uses her extraordinary talent to sniff through suspicious cargo at Bogota’s El Dorado International Airport. 

After her six-hour shift was over, Sombra was transported in a van with tinted windows back to her kennel. She is usually accompanied by two armed guards. “We are responsible for her safety,” said officer Jose Rojas, Sombra’s 25-year-old handler. Sombra’s detective work is needed now more than ever as Colombia wrestles with soaring coca production that is testing traditionally close relations with the US. A recent White House report found the amount of land where peasants and drug traffickers harvest the plant used to make cocaine rose 11 percent in 2017, despite $10 billion in US counter-narcotics work. 

President-elect Ivan Duque is promising a tougher approach to speed up eradication with strategies that could include aerial spraying and the use of drones. But even with advanced technology, experts say on-the-ground detective work like that performed by Sombra is critical. Some of Sombra’s recent busts include uncovering over five tons of Gulf Clan cocaine destined for Europe and concealed in crates of bananas. Officers also credit her incredible nose with more than 245 drug-related arrests at two of Colombia’s biggest international airports. 

“Her sense of smell is far beyond that of other dogs,” Rojas said. Drug cartels like the Gulf Clan have taken note. After learning there was a price on Sombra’s head, Colombia’s national police director ordered her to be transferred to a new post earlier this year, according to local news reports. Investigators uncovered the threat against Sombra through an intercepted phone call. “Sombra the German shepherd has become the terror of criminal organizations,” a recent story in Colombia’s El Espectador newspaper proclaimed.
