It sounds like she is critical by her stool description. Black, tar-like stool is typical with a parasitic infection. She needs supportive care (I.V. fluids) until a proper diagnosis is made. I suggest a Vet Hospital, not a local Vet. Balantidium Coli is treated with tetracycline, metronidazole, or iodoquinol (this is an anti-protozoal medication). I will assume all 3 were tried. Have they re-done her fecal exam? Stool must be re-tested to see if the parasite is still present. I suggest her fecal be examined for other parasites. Chryptosporidia, Giardia, etc. http://pets.webmd.com/dogs/dog-protozoan-diseases Any long term parasitic infestation will result in a long recovery. Supportive I.V., then small, mild, frequent meals. Many of these protozoa can infect humans. Re-infection is also a concern. Careful removal of all her feces from the yard and hand washing is important.

I don't have any experience with that, but you can try contacting a teaching vet school or human infectious disease doctor, eps since I assume she can infect humans with it. Sometimes they will want to help even if it's a dog. Sorry she's so sick. You can try posting this on the health forum on this site. No one can answer you back and forth in this section. There are some very knowledgable people there. Please include what breed, her age, and everything the vet has tried. Please keep us posted and good luck!
