Descending from some of the greatest runners on the planet, many domestic dog breeds can run even faster than their wolf ancestors. Descending from some of the greatest runners on the planet, many domestic dog breeds can run even faster than their wolf ancestors. While wolves top out at about 38 mph, and can maintain this speed only for short distances, some dogs run up to 20 percent faster than, and can maintain such a pace for relatively long distances. As a comparison, the fastest humans on Earth may attain speeds of 23 mph. An Australian Shepherd running on a path.
