As was said above, first you need to pick a stone from the ground or pretend that you are doing this if there is no stone around. Even if you have a stone, make the gesture that you take it from the ground.
Another important point is to do it quickly and aggressively with loud cry. Also you can pull back one’s arm with a stone.
The whole trick is that dogs are so afraid of stones that they will run away before you actually throw it or they see where it fails.
