Wet dogs can shake themselves about  70% dry in a fraction of a second. Their skin is so loose that it swings almost 90  degrees in either direction when they shake.

This helps their bodies conserve energy by not having to stay warm while waiting to dry off, because if dogs were not able to shake themselves dry, it would be like humans being unable to change out of wet clothes on a cold day.
