Hi Christian,
After reading the list of foods you tried, it doesn’t seem the vets gave you any guidance when they told you to switch food. If you can afford NB, it will be a good starting place to settle the GI system down.
It does sound like the rice is not agreeing with her, and it would be a good idea to switch to sweet potato or white potato. She may end up needing the Metronidazole. It must be given with food, and usually the vets prescribe Pepcid also because it can cause nausea. When you go back to the vet, make sure you tell them how she reacted to the Pepcid.
