What exactly did you do to get rid of the heartworms. I think my dog has had them for some time now. I saw the parsley, Wormwood , walnut etc.. in clarks book. How do you know how much to use on dog ( weight etc..) ? Also how long should the treatment last she just say week 5 and so on. How long did you follow this. Is this the only thing you did ( what was written on her chart) please be specific if you can. I have a little dog. thanks!
