But as the dog sniffs her way toward record cocaine interdictions, she has also become the latest target of Colombia's most powerful drug gang.
Six years ago, the feared Urabeños offered $500 to anyone who killed a police officer. She is usually accompanied by two armed guards.
Her usual handler Jose Rojas told Colombian News Agency RCN Sombra's "sense of smell is far beyond that of other dogs".
Sombra was originally posted to various ports on Colombia's Atlantic coast, where smugglers sent speedboats loaded with drugs north to the United States or across the ocean to Europe. 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 USA counter-narcotics work.
President-elect Ivan Duque promised a tougher approach on coca production during his election campaign, with strategies including aerial spraying and drones. But even with advanced technology, experts say on-the-ground detective work such as Sombra's is critical.

They returned Friday to find little more than ash. "That is kind of that new normal that we are dealing with in California". About 38,000 people were under evacuation orders, 5,000 homes were threatened and the fire was just 5 percent contained.

And the gang is offering a bounty of $70,000 for the canine's life, Colombia's national police said last week.
But the dog can handle the high profile, her owners have said.
News cited intelligence sources saying that the gang put a price of about C$91,000 on Sombra's head, and that the dog has been moved from the gang's operating centre to the airport in Bogota.
Sombra is a 6-year-old German shepherd who has been on Colombia's counter-narcotics police force since she was a puppy.
