canine leishmania

Hello,
9 year doberman 31 kilos.  Diagnosed with leash 2 years ago. Vet believes mother passed leash to pup in womb. Have used standard vet medication these last 2 years. She still has leash but not active. Now its time to move to MMS. Have just received empty capsules to add and administer  the MMS. Has anyone in this Forum had experience with Canine Leish? And the treatment? Especially long term treatment? Am nervous to do this.. Seeking experienced  advise. Anyone out there? Thank you Group
