The Dybowski's frog is fairly tolerant of human disturbance; however, it has been threatened across portions of its range due to heavy collection for use in traditional Chinese medicine
. It breeds in slow-moving and stagnant water, and when not breeding is most commonly found in woodlands. The species covers a wide altitudinal range, from sea level to 900 meters, and possibly higher.
Adult Dybowski's frogs have a body length of 4.5-7.5 cm. The head and body are relatively broad; the skin, generally smooth but with some small protuberances along the back.
