April is Heartworm Awareness Month, an important time to raise awareness about a dangerous and potentially fatal disease that affects dogs across the country. At Dogtopia of Fort Myers, we’re committed to keeping our pups safe, healthy, and happy—which is why we want to help you understand the risks of heartworm disease and how to protect your furry family member.

Heartworms are transmitted through mosquito bites and can live in the heart, lungs, and associated blood vessels of infected dogs. Left untreated, heartworm disease can lead to severe lung disease, heart failure, and even death. The good news? It’s 100% preventable.

What is Heartworm Disease?

Heartworm disease is caused by Dirofilaria immitis, a parasitic worm that is spread through the bite of an infected mosquito. Once a dog is bitten, the larvae mature into adult heartworms that can grow up to a foot long and cause serious damage to the heart and lungs.

Florida’s warm, humid climate makes it a year-round risk zone for mosquitoes, which means prevention isn’t just a seasonal concern—it’s something pet parents should be vigilant about all year long.

Signs and Symptoms of Heartworm Disease

In the early stages, heartworm disease may show few or no symptoms. As the disease progresses, signs can include:

Persistent cough
Fatigue after moderate activity
Decreased appetite
Weight loss
Swollen belly due to fluid accumulation
Labored breathing

If left untreated, heartworm disease can become severe and life-threatening.

Heartworm Prevention: Your Best Defense

The best way to protect your pup from heartworm disease is through consistent monthly prevention. Your veterinarian can recommend a safe and effective preventive medication in the form of pills, topicals, or injections.

Tips for Prevention:

Give monthly heartworm preventives year-round, not just during mosquito season.
Schedule annual heartworm tests to catch infections early—even if your dog is on preventive medication.
Eliminate standing water around your home to reduce mosquito breeding grounds.

What If My Dog Tests Positive?

If your dog tests positive for heartworm, don’t panic. While treatment can be lengthy and costly, it is possible. Your vet will develop a treatment plan that may include:

Restricting exercise to prevent further damage
Administering medications to kill adult and immature heartworms
Monitoring recovery through follow-up tests

Early detection and treatment improve your dog’s chances of a full recovery.

How Dogtopia of Fort Myers Keeps Your Dog Safe

At Dogtopia of Fort Myers, your dog’s safety is our top priority. While our play areas are fully indoors, we remain mindful of the year-round risk of mosquitoes in Florida and encourage pet parents to stay on top of heartworm prevention to protect their pups both at home and outdoors.

When in Doubt, Ask Your Vet

If you’re unsure whether your dog is protected against heartworm disease, schedule a visit with your veterinarian today. Preventive care is far less costly—and far more comfortable for your pup—than treating a full-blown infection.

Let’s work together this April to raise awareness and keep our canine companions safe from this preventable but dangerous disease.
