A team of sniffer dogs set up at a British airport at a cost of 1.25 million pounds ($1.7 million) have proved adept at discovering small amounts of cheese and sausages but not so good at finding smuggled drugs, a report said on Thursday.
An inspection of border security at Manchester Airport in northern England found that during a seven-month period, the six dogs had failed to find any illegal class A drugs, those considered the most dangerous such as heroin or cocaine.
The article is from 2016 about a 2015 study. There is a 0% chance any of those dogs are still working, and a high probability that there were a significant amount of changes made to the program since then.
