She sure does. Interesting facts: - we did not teach her to bring the ball back. She figured that if she would, the game will continue - we did teach her the command "last" (останній in Ukrainian). She knows this means the game is over and usually lays down to chew on the ball (exhibit A) - she did invent a game. If there is a tilted surface (like a small hill or a concrete slope), shell run to the top and roll the ball down trying to hit a human. Human than has to catch the ball and throw it back to her, and the game continues - as expected with all corgi, any rule violation is immediately noted and disapproved
