Peterbalds resemble Oriental Shorthairs. They have a hair-losing gene and can be born bald, flocked, velour, brush, or with a straight coat. Those born with hair, excepting the straight-coats, can lose their hair over time. They come in all colors and markings.
Members of the breed have a slim and muscular build. They have a narrow and long head with a straight profile, almond-shaped eyes, wedge-shaped muzzle, and large, set-apart ears. They have a long whip-like tail, webbed feet and oval paws that allow them to grasp objects and open levered doorknobs.
