Heartworm Treatment Cost in Wisconsin — FAQ
How much does heartworm treatment cost for a dog in Wisconsin?
Heartworm treatment in Wisconsin averages $1,380 in 2026 — 8% below the national average. The standard melarsomine protocol (3 injections over 2 months plus pre-treatment bloodwork, X-rays, and strict exercise restriction) typically runs $1,000–$2,500 total. Annual heartworm prevention costs $110 and is far less expensive.
Is there a cheaper heartworm treatment option in Wisconsin?
The 'slow kill' method (monthly ivermectin without melarsomine) is cheaper but takes 1–2 years, doesn't kill adult worms directly, and is no longer recommended by the American Heartworm Society due to resistance concerns. The standard melarsomine protocol at $1,380 in Wisconsin is the only AHS-approved treatment. Humane societies and veterinary schools sometimes offer discounted treatment.
What happens if heartworms are left untreated in Wisconsin?
Untreated heartworm disease is fatal. Adult worms grow up to 12 inches long inside the heart and pulmonary arteries, causing progressive heart and lung damage. Dogs with heavy worm burdens develop congestive heart failure within 1–3 years. In Wisconsin, heartworm prevention costs $110/year — about 8% of what treatment costs. Prevention is the clear choice.
