Drug Detector Dog
What are drug detector dogs?
detector dogs have a sense of smell far stronger than that of humans and a tendency to attack, obtain and possess prey. For these characteristics, they can detect even a slight odor of narcotic drugs.
How does a drug detector dog learn an odor of a drug?
A customs officer called a handler trains a dog for drug detection by playing with him using a "dummy" (a tightly rolled towel with a drug odor). By repeating this training, the dog gradually associates the odor of a drug with the dummy and with the the playing. Accordingly, the drug detector dog tries to detect a drug odor of a drug because they want to play with a handler using a dummy.
