I haven't had that problem. Gracie Ruth taught me how to play fetch. She'd bring a toy and drop it at my feet. I'd throw it, she'd get it and bring it back.
But then, Gracie loves to play this game. If you 'ignored' her when she doesn't bring it all the way back, do you think she'd get a toy and bring it to you? Or you could just sit down with 20 balls and throw one after another until they are all used up.
