What about using a roational diet with your dog so she doesn’t get bored? Finding 3 or so foods that work well with her and rotating every week or two so she stays interested. You could also look at using wet food toppers (cutting back some of the dry so she doesn’t put on weight) so there’s always something different and enticing her to eat. Just a spoonful or two mixed with the dry does the trick for a lot of dogs, and you can usually stretch the can about a week. I think I saw Farm & Fleet had several nice varieties of canned food, and Walmart also has their Pure Balance line and the Rachael Ray tubs.
