Guangzhou Customs drug detection dogs wow crowd at open day

In a second exercise, the host invited volunteers from the audience to pose as travelers pushing suitcases through a mock customs hall. Another Labrador, Lyle, weaved through the crowd with sharp focus and singled out the "drug trafficker" in under a minute. The dogs' precision and speed drew warm rounds of applause.

Karl and Lyle are seasoned pros in narcotics detection with more than six years of service.

According to a customs officer, drug detection dogs have been instrumental in recent anti-smuggling operations at Guangzhou's checkpoints, consistently locating drugs hidden in suitcases carried by passengers. In recent years, Guangzhou Customs has cracked 200 drug-smuggling cases with canine assistance, seizing over 180 kilograms of heroin, cocaine, marijuana, and other controlled substances.
