Key Takeaways
- Heartworms are transmitted through mosquito bites.
- The worms live in the heart, lungs, and associated blood vessels of infected dogs.
- They can cause severe lung disease, heart failure, organ damage, and ultimately death.
- Regular testing and preventive measures can protect your dog from this deadly disease.
Heartworm Transmission
When a mosquito carrying heartworm larvae bites a dog, it transmits the larvae into the dog’s bloodstream. In about six months, these larvae mature into adult heartworms. These worms can live for 5 to 7 years in dogs, and a dog can have as many as 250 worms in its system.
The Life Cycle of Heartworms
The life cycle of heartworms begins with the adult female worm releasing her offspring, called microfilariae, into the dog’s bloodstream. When a mosquito bites an infected dog, it picks up these microfilariae, which mature into infective larvae in 10 to 14 days. Here is a more detailed explanation of the heartworm life cycle.
Effects on Dogs’ Health
Heartworms lodge in the heart, lungs, and surrounding blood vessels, and begin reproducing. They can cause severe lung disease, heart failure, and other organ damage. Over time, these effects can lead to a dog’s death.

Symptoms of Heartworm Disease
In the early stages, many dogs show few symptoms or no symptoms at all. The longer the infection persists, the more likely symptoms will develop. Advanced cases can cause congestive heart failure. Dogs often cough, become lethargic, lose their appetite, or have difficulty breathing. If your dog is displaying these symptoms, it’s crucial to get them checked by a veterinarian.

Diagnosis and Treatment
Heartworm disease is usually detected through blood tests. Other diagnostic procedures may include x-rays and ultrasound.
Treatment is typically an arsenic-based compound to kill adult heartworms. However, the treatment is not without its risks and can be expensive. The best approach, therefore, is prevention.
Prevention is Better Than Cure
Preventive measures include heartworm preventive medication and mosquito control. Regular testing for heartworms should also be a part of your dog’s routine care. For more advice on preventative care, visit our dog health tips section.
