Normally when the sniffer dog is brought in, that nose is searching for drugs or weapons. But at Toronto's Pearson International Airport, customs agents were in for a real treat.
As the beagle worked over the luggage of a Canadian man returning from a trip to Russia, the Canada Border Services Agency uncovered 5,000 squirming, blood-sucking leeches.
The unnamed man wasn't arrested for smuggling but did get hit with illegally importing an internationally regulated species without permits and will head to court next month, reports National Geographic.
Apparently, leeches are back in favor, says USA Today, who reveals the FDA has approved the 2,000-year-old treatment for a variety of medical uses.
