I'm sorry to hear that Daisy is having so much trouble! Chronic diarrhea can be a very frustrating problem. It sounds like she doesn't have a specific diagnosis yet, so I would be interested to know exactly what testing has been done and what treatments have been tried so far - feel free to request a consultation if you want to discuss things in more detail. In general, some tests that may be helpful in diagnosing the cause of chronic diarrhea like this would include a fecal analysis for parasites (including less common ones like Giardia and cryprosporidium), general blood work to check for a systemic illness that may be causing the diarrhea, a GI blood panel to look at whether or not nutrients are being absorbed appropriately, and even endoscopy or exploratory surgery with biopsies in some cases to check for things like IBD (inflammatory bowel disease) or GI lymphoma. If a full diagnostic work-up is not an option financially, then some treatment options that could be tried would include a diet trial with a prescription hypoallergenic or GI diet, metronidazole, an oral steroid like prednisone, and vitamin B12 supplementation. I would recommend taking Daisy back to one of the vets who has seen her before to discuss options for where to go from here, or asking for referral to an internal medicine specialist if you prefer.
