Heartworm Treatment Cost in West Virginia (2026)

How much does heartworm treatment cost for a dog in West Virginia?

Heartworm treatment in West Virginia averages $1,200 in 2026 — 20% 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 $100 and is far less expensive.

Is there a cheaper heartworm treatment option in West Virginia?

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 $1,200 in West Virginia is the only AHS-approved treatment. Humane societies and veterinary schools sometimes offer discounted treatment.

What happens if heartworms are left untreated in West Virginia?

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 West Virginia, heartworm prevention costs $100/year — about 8% of what treatment costs. Prevention is the clear choice.
