The Pekingese is a breed of toy dog, originating in Western China. The breed was favored by royalty of the Chinese Imperial court as both a lap dog and companion dog, and its name refers to the city of Peking (Beijing) where the Forbidden City is located.

The breed has several characteristics and health issues related to its unique appearance. Because of its desirable characteristics, the Pekingese has been part of the development of designer crossbreeds, such as the Peekapoo (crossed with a poodle) and Peke-a-tese (crossed with a Maltese).

Modern breeders and dog show judges seem to prefer the long-haired type over the more traditional spaniel-type coat.

The Pekingese's flat face and large eyes are some of the breeds most obvious characteristics. The body is compact and low to the ground. Pekingese also have a muscular and durable body.

The breed's unusual rolling gait may have been deliberately developed by breeding to prevent the court dogs from wandering in ancient times. The Pekingese weigh from 7 to 14 lb (3.2 to 6.4 kg) and stand about 6–9 inches (15–23 cm) at the withers, however they can sometimes be smaller.

These smaller Pekingese are commonly referred to as "Sleeve" Pekingese or just "Sleeves". The name is taken from ancient times, when emperors would carry the smallest of the breed in their sleeves. A Pekingese over 15 pounds is disqualified in the show ring.
