Buy some meat and sweet potatoes and make her food. Maybe she'll eat some of that, and It costs the same as dog food. Dog food is full of poison in most cases.
Sometimes a sick pet has to sort of warm up to their food, so make some appatising smells for her and get her thinking food.
I had a cat that was nit by a car and his nose was messed up, he stopped eating, becasue he stopped being able to smell. Had to feed him bologna for months after that, its the only thing that smelled good to him after that accident.. Once I got him started on the bologna I could then get him to eat other food., but I had to be quick.
Try organ meat, just talk to the butcher and get some samples and test what she might eat
