Using a still image to imply motion, a similar technique to shooting prop driven airplanes can be used to show the motion of an animal or person running, it takes a steady hand to shoot when moving in a car in low light, mine? not so steady : )
A low shutter speed of around 1/60 of a second is about right to show Ducky's legs as blurred while keeping her head relatively sharp, auto ISO with a f/2.8 lens in low light worked out quite nicely for this series.
