Cloned dogs to sniff for drugs, explosives

The country that created the world's first cloned canine plans to put duplicated dogs on patrol to sniff out drugs and explosives.

The Korean Customs Service yesterday unveiled a group of Labrador retrievers being trained near Incheon International Airport, west of Seoul. The dogs were born five to six months ago after being separately cloned from an experienced drug-sniffing canine in active service.

Due to the difficulties in finding dogs who are up to snuff for the critical jobs, officials said using clones could help reduce costs.
