Apparently, she has had a bad case of heartworm. She is currently taking daily: hawthorn to keep her heart strong, chloroxygen to help increase oxygen levels, about 100 mg. of vitamin C and kidney rejuvenator to help her urinary system. She also takes dessicated liver capsule once a week. Then twice a month she gets a half dose of Ivermectin, about 5 mg of prednisone and doxycycline for about two days before through two days after the Ivermectin day. I know this is not the pure holistic way of dealing with this. But, since we have been using the somewhat lowered dose of Ivermectin with the prednisone, we have been able to keep on top of the heartworm load and not have to restrict her quite as much. This will likely be a slower road to rid her of this. But the strictly holistic road just was not working. She is much better and is coughing much less. I have had many discussions with my vets (both the holistic vet and the conventional vet) over this and we are all in a better place with this protocol.
