Lots of dogs like to play fetch and will often bring you the toy back and drop it at your feet. That’s great if dog does this but a few will bring you the toy and then as you go to take it they quickly run away with it. If they do this then ignore them, pick up and begin to play with another toy and just like your little annoying sister your dog will come back and want what you have. However, before they get it, ask them to sit and wait and then throw it. Keep repeating this until they get the message that they might as well just give it back.
