It can be costly and time-consuming to train police dogs when each candidate might have different skills and personalities. China's solution? Make copies of the best-performing dogs. The state-backed China Daily reports that the city of Kunming, the Yunnan Agricultural University and Beijing Sinogene Biotechnology are about to train Kunxun, a two-month-old Kunming wolfdog cloned from a "great" canine detective. The aim, as you might guess, is to save time and money -- they'll know that Kunxun is more likely to learn quickly and perform well.
