You could try a can or two to see if you can tempt her to eat - it certainly tempted my then-skinny dog - but don't plan to keep her on it long terms, due to sneaky low calories. \
Lost my post! Or did I?
In brief, try Hills I/D Chicken and Vegetable Stew. It really tempted my other small breed dog when he started to recover from his kidney issues. It is balanced, apparently more tasty than the solid "pate" form, has a few bits of peas and carrots, something shaped like chunks of burger, and gravy. But it is low in calories compared to other ID and other canned foods, so keep that in mind or she might lose weight while eating what seems like a normal volume of food. I don't think it's meant for long term use.
