Toppy (a portmanteau of "Tomorrow’s puppy")[1] is the name of the world's first cloned working dogs.[2] They are seven Labrador Retriever clones, and they were born in late 2007 to three surrogate mothers.[1] The project cost ₩300 million, and was funded by the Government of South Korea;[1] it was led by Lee Byeong-chun, a former aide to Hwang Woo-suk, who fell from grace after his stem cell research turned out to be fabricated.[3]
Each Toppy is a clone of a successful sniffer dog in Canada;[4] they needed 16 months of training to qualify to work for the South Korean Customs Service.[4] Only 10-15% of dogs are genetically predisposed to being effective detection dogs.[3]
