Police dogs are dogs specifically trained to assist law enforcement teams like the police force, investigation bureaus, crime and felony departments, and other government and federal agencies as well. The most popular breeds that are trained to become police dogs are German Shepherds, Doberman Pinschers, and Rottweilers. Other breeds like Boxers, Bullmastiffs, Labrador Retrievers, Terriers, and Bloodhounds are also trained to serve in this line of duty. A police dog is also referred to as a K-9 (a homophone for canine). The first ever Police K-9 units, which specialized in police dog programs, were formed in 1907 in the United States of America. New Jersey, South Orange, and New York City were the first ever cities that incorporated dogs on their police teams. Initially, police dogs were trained only to patrol, sniff out criminals in hiding, and locate missing personnel and property. With time, the scope of using a police dog's sensory prowess increased and they were being trained to specialize in drug and poison detection, search-and-rescue operations, bomb and explosive detection, and criminal tailing, tracking, and locating. Soon, specific dog breeds were being extensively trained to specialize in varied law enforcement tasks. Doberman Pinschers, Rottweilers, Belgian Malinois, American Pit Bull Terriers, American Staffordshire Terriers, and other muscular breeds are trained as public order enforcement dogs. These dogs, traditionally, chase a felon or a suspect who has tried to flee from a crime scene. Their image as a strong, sturdy, and well-built dog prevents the suspect from resorting to creating a threat or danger. Foxhounds, Schnauzers, Cocker Spaniels, and Basset Hounds are some breeds that are trained to become illicit substance detection dogs. Their strong sense of smell aids officers in sniffing out illegal substances like poison, drugs, weapons, or explosives. Australian Shepherds, Coonhounds, German Shepherds, and Labrador Retrievers are trained and developed as tracking dogs, their main objective being sniffing and tracking down missing objects, people, or trails of escaped convicts and felons. Labrador Retrievers, German Shepherds, Bloodhounds, and Beagles specialize extensively as cadaver-sniffing dogs. They possess extremely sensitive smelling skills. These dogs are used to sniff out decomposing bodies to locate corpses, dead bodies, and human remains. Their sense of smell is so strong that they can sniff out a body under running water, rivers, lakes, etc. Find more details about the top dog breeds that are used on the police force and by the law to avert, prevent, detect, and solve crime.
