Dogs are utilised in biological research because they have characteristics with humans that other animals do not. However, dogs are utilised in very few operations due to their parallels with humans, and they are only used when other animal models cannot produce meaningful findings.

Dogs have been excellent research subjects for various purposes for a long time. One of the factors contributing to dogs’ physiological similarity to humans is that their genome has been sequenced, and they share a similar number of genes with humans. Dogs are, therefore, especially helpful in genetic research.

The dogs are capable of carrying out their duties anywhere. Still, they are most frequently used to search for explosives and illegal drugs at airports, border crossings, large gatherings, and even in stopped civilian vehicles.

How Investigation Dogs Work

Although the exact date that humans domesticated dogs is unknown, it is known that people and dogs have coexisted for thousands of years. Dogs are now an essential part of many people’s life, serving as companions, search-and-rescue dogs, guide dogs, and bomb- or drug-sniffing canines, thanks to modern training techniques. Police canines, however, are asked to sacrifice more of themselves than most dogs.

Today, police departments in most big cities use Investigation dogs to find criminals, sniff out contraband, search buildings and perform other tasks that human police officers cannot perform as effectively as a dog. As a result, numerous dogs have sacrificed their lives to protect and serve, in addition to the thousands of dogs employed by force daily.

Sharp senses of Dogs

Everyone knows how much more perceptive we humans are compared to our closest canine buddies. Duke will start howling before you hear a siren pass. For this reason, Princess can tell if you have a treat in your pocket. A short while after the first wolves thought it could be a good idea to associate with people, people started devising uses for those canine senses.

Dogs are good hunters

Dogs have long assisted humans in hunting. In addition, they have aided in managing household animals. More recently, dogs have been commonly known to assist authorities in locating illegal narcotics, explosives, and criminal suspects. In addition, dogs are used to locate people who are stranded during disasters, and their great sense of smell also aids them in finding dead bodies.

In more recent times, individuals have discovered novel ways to use the extraordinary senses of dogs. Dogs can sometimes teach us, humans, about our capacities. Furthermore, smell and hearing aren’t the only senses. Some canines have the eerie ability to understand their owners’ physical and mental conditions.

What varieties of investigation dogs exist?

These days, police canines receive specialised training. This is because they are considered authorities in their field. Some of the specialised functions played by investigation dogs include:


Police canines trained specifically for tracking utilise their keen noses to find missing people or criminal suspects. Even the most sophisticated thief can be found by tracking dogs trained for years. Many suspects would flee from the police if tracking dogs were not used by force.

Chemical Detectors

Similar to tracking dogs, these police canines use their sense of scent to aid law enforcement. Drug-specific detection is the main goal of substance dogs. For example, some dogs are trained to identify explosives or bombs. In addition to being trained to find the explosive, these brave canines are also taught how to react (very carefully!) and safely inform their cop companion of its location. Other canines might concentrate on illicit drugs. These dogs assist authorities by saving them from carefully checking through luggage, a car, or other areas by immediately detecting the presence of illegal substances.

Public monitoring

These police canines aid police officers in keeping the peace. For example, to prevent criminal suspects from escaping, they may pursue and detain them until the police officer comes, or they may guard a facility (such as a jail or prison).

Cadaver Canines

These investigation dogs are taught to discover dead bodies, even though it seems a little nasty. Nevertheless, these dogs do a crucial job for the police force and do it well.

Training of a Dog

A canine must complete a basic obedience training programme before being accepted by an investigation agency. They must be capable of immediately following instructions from their handler. This gives the police total control over the dog’s force when confronting a suspect. In Europe, dogs frequently receive commands during training in the local tongue. In contrast to retraining the dog to learn new orders, it is simpler for the officer to learn new words or commands when the dog has already been taught this language for fundamental behaviour. Contrary to common perception, investigation dogs are not taught to speak the same language as their handlers. This is done to prevent suspects from using the dog against the officer.
