MERIDIAN TOWNSHIP - Yukon is a drug sniffing police K-9 unit trained by K-9 instructor Hector Hernandez. His handler, Officer Andrew Tobias, helps Yukon's sense of smell stay sharp by planting drugs inside cars in their compound. Once the drugs are hidden, it's Yukon's job to find the drugs by detecting trace scents of the narcotics. Officer Tobias then gives specific commands to Yukon in Hungarian.

A dog's nose is thousands of times more sensitive than a human's. Dogs are able to detect microscopic particles in the air, and once Yukon finds what he's trained to sniff for, he pin points the source by sitting next to it.

It's near impossible to hide drugs from dogs like Yukon, because he is reward driven. He will find what he's sniffing for because he wants Tobias to throw his tennis ball as a reward.
