Miniature Shar Peis have a shoulder height up to 43 cm (17 in) and weigh up to 17 kg (38 lbs). Like their larger brethren, they are known for their blue-black tongue and profusely wrinkled head, neck, and shoulders. They have large heads with small, highly set ears, and thick tails which curl over the back. Miniature Shar Peis have large, wide muzzles, and small, sunken eyes. Puppies have wrinkles all over their bodies.

The Miniature Shar Pei is affectionate, adaptable, playful, confident, calm, independent, regal, and alert. They are inherently clean and quiet. Some can be a bit aloof and though they are wise, obedience training requires a confident, consistent authority figure to prevent them from becoming overly dominant. This breed makes a delightful companion but is very independent with a temperament that will depend highly on how the owner treats the dog. It is a dog that bonds well with its family and is very devoted. Daily walks are needed to give the dog some exercise. During times of increased temperature walks should be shortened as these dogs are somewhat sensitive to the heat.
