First, give her her normal food. Leave it out. Don't give her special treatment because this teaches her that if she doesn't eat, she gets treats. When she gets hungry enough, she'll eat.
The best answer is to exercise her and well, before you feed her, a well run dog is a hungry dog. she will eat from a bowl of you do not give into her OK. she just has to be trained to do it , she thinks eating from your hand is normal and acceptable behavior, she has to be taught it isn't.
She may even go a couple of days without eating and lots of crying and whining, as she knows no different, but do not give in here OK, she will eat when she is hungry.
Its going to be hard on you, and this is really about re training you as much as it is your dog, in the nicest possible way, please take no offense to that comment. Lots of exersice is the key and make sure she is drinking enough.
