Overview
Heartworm disease is a potentially fatal condition caused by a parasitic worm known as Dirofilaria immitis. These worms can reside in the heart, lungs, and associated blood vessels of affected animals, leading to severe lung disease, heart failure, and damage to other organs.
Causes
Heartworms are transmitted through the bites of infected mosquitoes. Once a dog is bitten by an infected mosquito, the larvae migrate through the animal’s body and settle in the heart and lungs.
Symptoms & Signs
Early Symptoms
- Mild persistent cough
- Fatigue after moderate activity

Diagnosis
Diagnosis typically involves a blood test to detect the presence of heartworm proteins, and may also include X-rays, echocardiography, or ultrasounds to assess the extent of the infection.

- Regular veterinary check-ups
Prognosis & Recovery
The prognosis depends on the severity of the infection and the dog’s overall health. With early detection and treatment, many dogs recover well. However, severe cases may have long-term health impacts.
