Swimming Like a Dog
Children generally manage to swim like a dog in their initial attempts. This is a very easy and simple method of propulsion, mainly for the reason that the arms and legs are never lifted above water.
Legs are kicked out straight to the rear, sole of each foot striking the water squarely and alternately, instead of working together. Hands are placed in front of the body, with palms down, and are successively brought down under the body and up again.
