All Shar-Pei, but especially the horsecoat need early socialization with children, strangers, and other animals. They can be stubborn, strong willed and very territorial. Early training can help control these traits before they become problem behaviors. Some people may experience a sensitivity to the harshness of the coat of either length. This is a mild, short lived rash, that can develop on the skin that has been in contact with the coat, most commonly on the forearms.
