Does she eat it or not? My Shih Tzu has a somewhat similar attitude as your dog. She would pick out the food and bring it in one corner. Then, she would go back to her bowl and pick another one to bring it in the corner. Once she's done, she would go to that corner and eat it- even when she eats her meals alone (without any pack intrusion).

I think it's one of your dog's quirks. As long as she eats it and it doesn't get dumped on somewhere unsanitary, I think you can leave her be in the mean time. After all, she does clean it up.
