Heartworm & Natural Dewormers

Heartworm is a parasite called dirofilaria immitis.

  • Parasites increase in the body when there are heavy metals in the bloodstream. They act as biological cleanup system to protect the host from organ toxicity. See 'Explore' > 'Toxicants' > 'Heavy Metals' This system is also related to biofilm.

  • The standard synthetic "treatment" includes (Immiticide/Melarsomine), an arsenic-based compound. Meaning, the standard "cure" for heartworm actually adds more heavy metals into the body. What the treatment looks like:

    • Doxycycline (10 mg/kg) for 28 days — to kill Wolbachia bacteria inside the worms

    • Macrocyclic lactone (heartworm preventive) starting day 1

    • Three injections of melarsomine (2.5 mg/kg IM) — the AHS recommends the 3-dose protocol for ALL dogs (99% efficacy), not just severe cases

    • Prednisone* taper injections

      • *Glucocorticosteroids including prednisone cause Iatrogenic Cushing's by flooding the body with cortisol-like hormones at very high levels, shutting down pituitary signal, causing adrenal glands to atrophy while the dog's body experiences all the effects of excess cortisol — pot belly, hair loss, thin skin, muscle wasting, high blood sugar, and frequent urination. Adrenal recovery can take months if not years after stopping and immediate withdrawal can cause life-threatening adrenal crisis.

    • Diroban (melarsomine, Zoetis/Anzac) was FDA-approved in June 2026 as the first generic alternative to Immiticide, addressing long-term shortage issues.

    • A non-arsenic alternative (moxidectin + doxycycline "Moxi-Doxy" protocol 😡) is listed in the Merck Vet Manual as an option if melarsomine is unavailable or contraindicated, but is not the standard and takes much longer (up to 2+ years) with a higher risk of lung disease progression.
