Six white male dogs collectively named Toppy reported for duty at a training facility for sniffer dogs run by the Korea Customs Service in Yeongjongdo.
Chase, the father of the dogs, and his six sons look exactly the same -- because the sons were cloned, born to surrogate mothers via the transfer of the nucleui of Chase’s somatic cells.
“Toppy” is a compound name meaning “tomorrow’s puppy”; the Toppies are numbered one to seven to tell them apart. The Korea Customs Service commissioned the cloning project because they thought that training clones of an effective sniffer dog would be easier than training ordinary dogs, which may or may not have the right genetic makeup for the job.
