What are heartworms?

Heartworm disease is very common—it’s been reported in all 50 states.1

Nearly 300,000 dogs in the US contract heartworms each year from infected mosquitoes, causing lack of energy, weight loss, and breathing problems. If left untreated, then heartworm disease can cause heart and lung damage and even death.2

Both indoor and outdoor dogs are at risk year-round—no matter where you live. Annual screenings with a simple blood test are important to help detect heartworm disease.
