 The Guangdong province in China was also a popular trading place during the Han dynasty, and it is unclear if the Shar-Pei was brought to China, or if it was originally bred in China.The Shar-Pei's loose skin and extremely prickly coat were originally developed to help the dogs fend off wild boar, as they were used to hunt.Later, the breed was used for dog fighting; these enhanced traits made the Shar-Pei difficult for its opponent to grab and hold on to, and so that if it did manage to hold on, the Shar-Pei would still have room to maneuver and bite back; when grabbed by any loose wrinkle, a Shar-Pei can actually twist in their skin and face in their opponent's direction.
