Hi, this is Dr. Gabby. First you need to figure out the cause of the diarrhea before you choose a food.
There are many causes of diarrhea such as:
Gastrointestinal parasites like worms, giardia, and coccidia
Gastrointestinal bacterial infections
Food allergies or food ingredient intolerance
Inflammatory bowel disease
So I would start with a fecal test and blood work.
If you just want a general diet to feed her when she has diarrhea use plain cooked chicken.
Does that help? Do you have any additional questions?
