What can police dogs detect?
Dogs have apocrine glands all over their bodies, but the highest concentration is found in the genitals and anus, hence why they sniff each other’s butts. … Most mammals have apocrine glands, including humans. For humans, these glands are concentrated in the armpits and genitals.
The animals help law enforcement by detecting the presence of illegal substances like ice, ecstasy, speed, cocaine and heroin. An indication from a sniffer dog can be enough for police to search you for drugs. (An indication is when a dog signals to its handler – by sitting down, usually – that it smells something.)
Sniffer dogs have totally no interest in the drugs themselves. What they’re actually searching for is their favourite toy. Their training programme has led them to associate that toy with the smell of drugs.
Research from New South Wales shows that the margin for error of sniffer dogs as much as 63%. And here’s why: the purpose of police dogs is to detect people in possession of drugs.
We’ve all felt the immediate panic ensure after spotting a drug-sniffing dog in full uniform…even if there’s nothing on us. “Wait, can this dog smell the blunt I had last night?” The truth is, it probably can — but does it even matter if it’s legal marijuana we’re talking about? Nothing illegal to see here, boys. Keep moving. With legal marijuana taking over the United States and Canada, are drug-sniffing dogs out of a job? Let’s explore this a little further.

I mean, that kind of sounds like heaven.

At this point, police officers are well aware that legal cannabis is taking over. It’s only a matter of time before everyone jumps on board. With the laws changing so fast, it’s still too early to tell how many drug-sniffing dogs will leave the business. If and when they do, it’s common for the dogs to retire to the homes of their handlers — the courageous men and women who know them best and have often raised them since they were puppies. It’s a happy ending for everybody! We get legal cannabis, the police have less work on their plate, and the drug-sniffing dogs get to live out their days in peace. Turns out, airports might not be such a stressful place in the future after all.
Here’s what professor Penny has to say. “If what [the dogs] are smelling is a product that people are legally entitled to possess, then that raises the question of whether the police would then have grounds to obtain a warrant to open the container or conduct a search of the location.” In his eyes, the next step is taking this dilemma to court.
