Mosquito season has started in Arlington—here’s how to protect your pet before risk increases.


April is Heartworm Awareness Month, and warmer weather brings increased mosquito activity across Northern Virginia.


This increases exposure risk for all pets, including those that live indoors.


What Is Heartworm Disease?

Heartworm disease is a mosquito-borne infection where parasites develop in the heart, lungs, and blood vessels.


After transmission, the parasites mature over several months and can live for years, causing progressive internal damage.


Why Prevention Matters

Heartworm disease often develops without early symptoms, making prevention the most reliable protection.


Once established, it can lead to:

  • Reduced stamina

  • Respiratory strain

  • Lasting organ damage

  • Serious complications if untreated


In cats, even a small number of worms can cause severe respiratory disease, and there is no approved treatment.


Are Indoor Pets at Risk?

Yes.


Mosquitoes can enter homes, exposing pets regardless of lifestyle.


Exposure only requires a single infected mosquito bite.


Signs to Watch For

Symptoms typically appear after the disease has progressed.


Dogs:

  • Mild cough

  • Fatigue after activity

  • Decreased appetite


Cats:

  • Coughing or asthma-like symptoms

  • Vomiting

  • Difficulty breathing


How to Protect Your Pet

  • Use prevention year-round

  • Schedule annual testing with your veterinarian

  • Give doses consistently


Missing even one dose can reduce protection.


Discuss With Your Veterinarian

Ask your veterinarian about a comprehensive parasite prevention plan, which may include:

  • Heartworm prevention

  • Flea and tick preventatives

  • Combination products for broader protection


Examples your veterinarian may discuss:

  • Heartgard Plus

  • NexGard

  • Simparica Trio

  • Revolution Plus


Your veterinarian will recommend the best option based on your pet’s health and lifestyle.
