2nd law – motion in a straight line unless compelled to change its state by the action of an external force – .the dog’s line of direction moved in a straight line initially, but this changed due to the force of gravity on it (as with its owner)... 3rd law says that for every action (force) in nature there is an equal and opposite reaction so the owner dived upwards into the sea and was then forced downward into the water, and the dog copied what it saw apparently following its owner ! The actions were repeated many times.
