I would fast her for 12 hours or so to give her gut a rest before trying to feed her again. At that point, atart with a SMALL amount of white rice and boiled chicken, and if that stays down, a little more. After a day or so of bland diet,small amounts of regular food at first working up to normal meals.

Make sure she's drinking, as stated before. Some dogs like ice chips, so those can be offered if she's not drinking.
