Explanation:
Work is done when the ‘object moves in the same direction as the force’ an example being a man walking up a flight of stairs carrying a box of weight.
Work is not done when the direction of the applied force and the direction in which the object moves are PERPENDICULAR to each other. An example being A man carrying a load while walking, no work is done on the load in the upward direction as the load is only moving horizontally.
Thus the answer is whenever she pulls the puppy towards her
