Heartworm disease in dogs is treated with a series of melarsomine (Immiticide) injections to kill adult worms, combined with strict exercise restriction for several months. Treatment costs $500–$1,500 depending on disease severity. Prevention ($5–15/month) is far less expensive and more humane than treatment.

Dear Pet Owner,
Looking for dog heartworm treatment? Costs can vary significantly between clinics. One clinic may charge $500 while a specialty practice might charge $1,500. Both may offer quality care — the key is knowing your options.
Heartworm prevention costs $60–$180/year vs. $500–$1,500 to treat. Treatment requires 2–3 months of strict rest — no running, jumping, or stairs — which can be very challenging. The slow-kill method (monthly ivermectin alone) takes years and is not recommended.
Pre-treatment diagnostics (microfilaria test, X-rays, bloodwork), doxycycline pre-treatment, melarsomine injections, prednisone, ivermectin, and follow-up testing at 6 months.
