The Kyi-Leo reaches 8-12 inches in height and 9-14 pounds in weight. It has a long silky coat, most commonly black and white but sometimes gold and white, which tends to grow to long lengths (never quite reaching past the floor) if tended properly. Its hair also grows on its face and tail. It has small yet delicate legs that are prone to damage if dropped, but the Kyi-Leo can be very agile and quick. The Kyi-Leo has notable similarities, in body size, shape, and hair, to the Shih Tzu dog breed though the eyes are more human set rather than bulging and they do not have the short-snout face.

The Kyi-Leo is generally calm, obedient, quiet, and difficult to provoke. It is usually very playful and active around trusted humans or animals, but tends to stay cautious and alert around strangers. Its acute hearing makes it a decent watchdog. It ideally lives in indoor settings and can be very patient when left alone for long hours at a time.
