At this point, it sounds like it's getting dangerous--if she dehydrates further, things will get scary. Have you started her on a probiotic or slippery elm? If they've had no effect, a fecal should probably be run to rule out other causes than the meds. There are causes of diarrhea that don't involve catching something outside--response to toxins, exposure to indoor varmints (mice are a big problem this time of year), even just intestinal imbalance, all of which can usually be detected through fecal examination and blood work. But prolonged diarrhea can cause dangerous dehydration after a few days....
