The horse-coat is generally thought to be more active and predisposed to dominant behavior than the brush-coat. The brush-coat variety has slightly longer hair and a smoother feel to it. The brush-coat is generally considered to be more of a 'couch potato' than the horse-coat. This breed sheds normally twice a year. The traditional Shar-Pei that is most popular in China is more faithful to the history of the breed (taller, less wrinkly, a flatter mouth and nose, horse-coated). As puppies, they have lots of wrinkles and as they get older, they have fewer wrinkles. Most adult Shar-Pei puppies need early socialization with children, strangers, and other mammals. The Shar-Pei is often suspicious of strangers, which pertains to their origin as a guard dog. Even friendly and well-socialized individuals will retain the breed's watch dog proclivities (like barking at strangers). It is a largely silent breed, barking only when it is playing or worried. The Shar-Pei were originally bred as palace guards in China.
