Full clinical detail
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.

Early Symptoms
- Mild persistent cough
- Fatigue after moderate activity
Advanced Symptoms
- Swollen belly
- Difficulty breathing
Emergency Signs
- Collapse
- Sudden onset of labored breathing
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.
Treatment Options
Home Care
- Restrict exercise
- Maintain a calm environment
Veterinary
- Medications to kill adult worms
- Antibiotics for bacterial infections
Surgical
- Surgical removal of worms in severe cases
Home Care
Dogs with heartworm disease should have restricted physical activity to reduce stress on their heart and lungs.
Prevention
- Monthly heartworm prevention medications
- Regular veterinary check-ups
Prognosis & Recovery
