Pour a little bit of plain chicken broth (no onion) over it.
Try canned and kibble.
Feed meals twice a day (or whatever your vet recommends) pick up if she shows no interest after 10 minutes, store in the fridg and offer at the next meal time.
It’s okay if she skips a meal or two as long as she is drinking water. If she goes 72 hours without eating solid food I would call the vet (something else may be going on).
Try to wait her out, it’s not mean. Most dogs will only skip about 2 meals.
PS: Poor appetite, nausea could be a symptom of liver disease. Talk to your vet about meds that may help.
