The Shar-Pei is self-assured, serious, independent, stubborn and very much self-possessed. Although not particularly demonstrative, it is devoted and very protective of its family. It is reserved, even suspicious, toward strangers. It can be aggressive toward other dogs and may chase livestock and other animals, although it is generally good with other family pets. The Shar-Pei needs daily mental and physical stimulation, but its needs can be met with lively games throughout the day or a good long walk. It is not generally amenable to exclusive outdoor living, but it can divide its time between house and yard. The coat needs only weekly brushing, but wrinkles need regular attention to ensure that no irritations develop within the skin folds.
