I have heard the following sentence in Narcos (a TV series which takes place in Colombia):
Cómo que le tumbaron con ese perro?
Context: Pablo Escobar bets with his partner Gacha that Gacha's drug-sniffing dog wouldn't be able to detect the cocaine mixed with the glass fiber in a hull of a boat. When the dog indeed doesn't detect the cocaine, Pablo says the line above.
What does "tumbar" mean in this context? The meanings of "tumbar" I see in the Word Reference dictionary are "to knock down", "to incline".
