Dogs Are Great Disease Detectors Army Dog Center Multan. A detection dog or sniffer dog is a dog that is trained to use its senses to detect substances such as explosives, illegal drugs, wildlife scat, currency, blood, and contraband electronics such as illicit mobile phones. The sense most used by detection dogs is smell.
Before RASCO, the Kenyan port was already using dogs to investigate containers, leading to 26 seizures in just six months. But sniffing 2,000 containers per day was slow and the dogs often got hot and fatigued. According to a video accompanying Jane Dalton’s piece at The Independent, it may take hours for inspectors to completely empty a container and locate the often cleverly concealed ivory.

With the new method, the dogs can smell the filters from comfortable, climate-controlled rooms and examine a container’s scent within a few minutes. Hunting dogs that search for game, and search dogs that work to find missing humans are generally not considered detection dogs. There is some overlap, as in the case of cadaver dogs, trained to search for human remains.
A police dog is essentially a detection dog that is used as a resource for police in specific scenarios such as conducting drug raids, finding missing criminals, and locating stashed currency. Dogs trained to detect the scent of illegal substances are useful as they can utilize their acute sense of smell to penetrate many hiding places which are inaccessible to other detection methods. A dog has about 200 million sensitive cells in its nose, compared to about five million or so in a human being, and therefore, a dog’s olfactory system is around 40 times more sensitive than that of a human.
A dog’s sense of smell is made even keener by an organ in the roof of the mouth that is not found in the human olfactory system and this enables it to “taste” a smell, amplifying a weak smell into a stronger one. This sensitivity to, for example, the odor of butyric acid emitted in sweat, enables a dog to locate an object, such as a ball, belonging to its owner from several similar objects thrown by a number of different people. It also enables tracking dogs such as bloodhounds to pursue and keep pace with a fugitive for up to 100 miles.
Dogs also have the ability to distinguish individual odors when other strong smells are also present. They can be trained to detect the odors of heroin, marijuana and cocaine hidden in suitcases even in the presence of strong smelling perfumes. Drug traffickers are constantly attempting to find more sophisticated ways of smuggling illegal drugs and the scenting abilities of sniffer dogs often provide the only means of locating well-hidden narcotics. Canine drug detectors have proved so successful that they are now employed in many airports and also at bus stations, border crossings, and ports.
The dogs are trained both to detect the drugs and then to alert authorities, either by pawing at the surface near the location of the smell or by sitting down next to the source. This behaviour usually provides the authorities with a valid cause to search luggage or vehicles.
