Heartworm Prevention 101

Heartworm disease is deadly, expensive to treat, and 100% preventable. A monthly tablet or topical is all it takes.

What Is Heartworm?

Heartworms are foot-long parasites that live in the heart, lungs, and blood vessels of infected dogs. Transmitted by mosquito bites, they cause severe lung disease, heart failure, and organ damage. Treatment is risky, painful, and costs $1,000+. Monthly prevention costs as little as $5 per dose.
