Drug dogs have an estimated 125 to 300 million olfactory receptors, depending on the breed and their olfactory bulbs in the brain are much larger than humans

Labrador Retriever 

The Labrador Retriever is one of the most popular breeds for single purpose drug detection work. Known for their friendly nature and intelligence, labs have an extraordinary sense of smell, making them highly efficient drug detectors.

However, due to several hereditary issues such as hip dysplasia and degenerative myelopathy, many agencies have been replacing aging German Shepherds with Belgian Malinois or Dutch Shepherds.

How are drug dogs trained to smell drugs?

There are many ways to train drug dogs to smell for drugs. The most common process is called imprinting.

A dog can be imprinted on almost any scent whether illegal or not. This is how dogs can smell nicotine and tobacco as well as the chemical substance in magic mushrooms. They can even detect cell phones in prisons and jails.

For a comprehensive list of what drugs these breeds can detect head over to our post titled “What Can Drug Dogs Smell?

During the imprinting process, a specific odor is presented to the dog in a tube or a scent box. When the dog’s nose hits the tube with the odor, a verbal marker or clicker is used and the dog is then rewarded with either food or a toy. Repetition of this process is how the dog learns to sniff out specific drugs.

Sometimes a scent training wheel, which is a large wheel that contains numerous boxes on the end of each arm is used. The arms each hold a container, one of which is loaded with the target odor. The drug dog is marked and rewarded when it smells the box with the target odor.

Once the dog correctly identifies the specific odor they are then trained to perform a final response to the target odor. In most cases, for drug dogs, this response is to sit and stare at the source of the target odor. Less commonly, some drug dogs are trained to scratch.

Which is the best drug sniffing dog breed?

Drug-sniffing dogs, regardless of their breed, play an invaluable role in law enforcement efforts to combat drug trafficking. 

Whether it’s the Labradors’ intelligence, the German Shepherds’ versatility, the Belgian Malinois’ agility, the German Shorthaired Pointers’ drive, or the Beagles’ compact size, each breed brings its unique strengths to the table. 

The dedication, training, and exceptional olfactory abilities of these canine heroes contribute significantly to the safety and security of our communities.
