LuAnn works in an are where "drug dogs," a special type of police dog is warranted.
She mentioned one dog that could tell if the person had drugs in their system before the urine test. The dog would lay right beside the person who had drugs in their system.
"People often wonder if dogs sniff out hidden drugs because they want to eat them, or because they're addicted to drugs themselves. In fact, the dogs have absolutely no interest in drugs. What they're actually looking for is their favorite toy. Their training has led them to associate that toy with the smell of drugs.
A dog named Breston uncovered a shipment of marijuana in heat-sealed Mylar bags, inside plastic-lined crates sealed with foam sealant, inside a closed storage garage.
The toy used most often is a white towel. Police dogs love to play a vigorous game of tug-of-war with their favorite towel. To begin the training, the handler simply plays with the dog and the towel, which has been carefully washed so that it has no scent of its own. Later, a bag of marijuana is rolled up inside the towel. After playing for a while, the dog starts to recognize the smell of marijuana as the smell of his favorite toy. The handler then hides the towel, with the drugs, in various places. Whenever the dog sniffs out the drugs, he digs and scratches, trying to get at his toy. He soon comes to learn that if he sniffs out the smell of drugs, as soon as he finds them he'll be rewarded with a game of tug-of-war.
As training progresses, different drugs are placed in the towel, until the dog is able to sniff out a host of illegal substances. The same method is used for bomb-detection dogs, except various chemicals used to manufacture explosives are placed in the towel instead of drugs.
A story recounted in "Dogs On the Case," by Patricia Curtis, tells of a drug dog that was a little too eager for a game of tug-of-war. While walking along a line of cars waiting to enter the United States from Mexico, one of the dogs alerted to the smell of drugs, slipped her leash, and ran down the line of cars. Before her handler could find her, she trotted back into view, holding a large brick of marijuana in her jaws. Although the border patrol had no way to tell which car the drugs came from, the dog still got her tug-of-war. She did her job and the drugs were off the street."
I always knew dogs had a good sniffer but that is pretty good sniffing.
We had a drug bust at the last school I worked at. One of the teachers bought a Corvette at a good price and the dogs hit all over it. It turned out that a former owner was a drug dealer.
The next time your dog goes to sniffing, think about the implications.
