Dogs can't sleepwalk like humans (moving around in a coordinated way that outwardly resembles normal “awake” behaviour). They are more prone to random, jerky movements while asleep, such as paddling their legs (as if dreaming of running) or, at most, perhaps lurching a few feet before flopping to the ground.
