When we adopt pups to people we let them know that the pup might not eat for a few days. That is very, very common. The worst thing to do is to keep offering other foods, especially table foods that could end up making them sick.
My advice is to put the food down twice/day and leave it for about 15 minutes. Pick it up if she does not eat it. She will learn that there are specific meal times. Usually only a day or two of that and they begin to eat.
