Dogs On Patrol
The Dogs Have It
While a police dog is on a drug sweep, he can cover a lot of area very quickly. It
would take human officers 10 times as long to search the same area, and they'd still never find everything a dog can sniff out.

Why do we bother using police
dogs at all? For one thing,
their sense of smell is almost 50 times more sensitive than a human's. A dog can sniff out criminals,
drugs, weapons, and bombs in situations where a human officer would have to search every inch, a dangerous task. In one case,
Breston, a Belgian Malinois who works with the Cheektowaga Police Department in Cheektowaga, NY (a suburb of Buffalo), easily sniffed out a shipment of
marijuana in heat-sealed Mylar bags, inside plastic-lined crates sealed with foam sealant, inside a closed storage garage. With his sensitive
nose and a search warrant, Breston kept $3,400,000 worth of drugs off the streets.

In addition to sensitivity, a dog's sense of smell is picky. It can discern a specific scent even when there are dozens of other scents around. Drug smugglers have tried to fool drug-sniffing dogs by wrapping drugs in towels soaked with perfume, but the dogs find the drugs anyway.
Breston's nose has about 200 million scent-receptor cells. A human's nose has about 5 million.

A police dog's work isn't all about his nose, though. The intimidating growl of a well-trained German shepherd can cause many criminals to surrender instead of running or fighting. "When I bring out the dog, all of a sudden they know they can't reason with him, they can't intimidate him, they can't try to scare him," said Officer Dan Smith, Breston's handler. The very presence of a police dog can prevent physical confrontations.
When a conflict does arise, dogs are faster and stronger than most humans, able to catch a fleeing criminal and clamp down with powerful jaws to apprehend the suspect until other officers arrive. Dogs have more than earned their place in the police forces of the world.

History of Police Dogs
European police forces were using bloodhounds as early as the 18th century. It wasn't until World War I that countries like Belgium and Germany formalized the training process and started using dogs for specific tasks, such as guard duty. The practice continued through World War II. Soldiers returning home brought news of the well-trained dogs being used by both sides of the conflict. Soon, K-9 programs were begun in London and other cities across Europe. The use of police dogs didn't gain a foothold in the United States until the 1970s. Today, police dogs are recognized as a vital part of law enforcement, and the use of police dogs has grown rapidly in the last five years.
