A trained sniffer dog can smell marijuana seeds as far as 15 feet. Plus, the residual marijuana smell on clothes can still be detected two days after exposure.
Sniffer dogs, also known by the name of narcotic detection dogs are trained to use their senses, particularly the sense of smell to detect a variety of drugs.
Actually, sniffer dogs have no interest in illegal drugs per se but what they search for are their favorite toys. The rigid training programs have led them to associate drugs with their toys.
In this section, let us enter the world of drug detection dogs. Let’s talk about issues like training programs, the substances that they can detect, and which dog breeds are excellent at smelling drugs.
The Training Methods Of Narcotic Detection Dogs
The first step in training a puppy is to play a game of fetch using the puppy’s favorite toy. In most cases, the toy is an unscented white towel. Eventually, some drugs are rolled inside the white towel until the dog learns to associate the smell of the drug with that of its toy.
The next step is to hide the toy in different areas of the room. The dog, with its keen sense of smell, will look for the towel. If done successfully, the dog is rewarded with treats.
To move on to the next level, the towel is hidden in areas where it is more difficult to locate such as inside a container or tucked in a faraway area. Also, narcotic detection dogs are trained to smell drugs at public events, multi-occupancy premises, borders, and boundaries.
In the eyes of these dogs, finding the traces of illegal drugs is a game from which they will be rewarded.
