Dog Killer: How to Prevent and Treat Heartworm Disease in Florida Pets

Dog Killer: How to Prevent and Treat Heartworm Disease in Florida Pets

Living in sunny Florida means we get to enjoy warm weather nearly all year long—and so do our pets. But with the sunshine and coastal breezes come some pesky tagalongs: mosquitoes. While they’re a common nuisance, mosquitoes also pose a serious health risk to pets in Pensacola and throughout Escambia County by spreading heartworm disease.
Heartworm disease is a preventable but potentially life-threatening condition that every Florida pet parent should be aware of. At Olive Branch Pet Hospital, we’re here to help you understand the signs, know the risks, and take proactive steps to protect your pup.

What Is Heartworm Disease?

Heartworm disease is caused by a parasitic worm (Dirofilaria immitis) that’s transmitted through the bite of an infected mosquito. When a mosquito carrying heartworm larvae bites your dog, the larvae enter the bloodstream and begin a slow journey toward the heart and lungs. Over time, they develop into adult worms, which can cause significant damage to these vital organs.
If left untreated, heartworm disease can lead to severe lung disease, heart failure, and other complications—sometimes even proving fatal.

Why Florida Dogs Are at Higher Risk of Contracting Heartworm

Florida’s tropical climate is the perfect breeding ground for mosquitoes. Unlike other parts of the country where mosquito season may be limited to spring and summer, Florida pets face exposure nearly year-round. Even indoor pets aren’t entirely safe, since mosquitoes can easily find their way inside.
That’s why heartworm prevention is so important for pets in Escambia County—especially those living in and around Pensacola, where mosquitoes thrive.

Signs Your Dog May Have Heartworms

Early on, heartworm disease often shows no symptoms. But as it progresses, you may notice:
  • A mild but persistent cough
  • Fatigue after moderate activity
  • Difficulty breathing Weight loss or decreased appetite
  • A swollen belly due to fluid buildup
  • In advanced cases, fainting or collapse
  • How to Protect Your Dog from Heartworm Disease

    The best way to deal with heartworm disease is to prevent it before it starts. Here’s how you can protect your pup:
    – Keep them on year-round prevention. Monthly chewables, topicals, or a longer-lasting injection can prevent infection even if your dog is bitten by an infected mosquito.
      – Test annually. Even dogs on prevention need regular testing to catch any potential infections early.
        – Reduce mosquito exposure. Eliminate standing water, use pet-safe mosquito repellents, and keep pets indoors during peak mosquito hours when possible.

    What If My Dog Tests Positive for Heartworm?

    If your dog tests positive for heartworm, don’t panic—but do take it seriously. Heartworm disease is treatable, especially when caught early, though the process can be complex and requires careful management. At Olive Branch Pet Hospital, we create a personalized treatment plan based on your dog’s health and the stage of the disease. Treatment typically includes medications to eliminate the worms, strict activity restriction to reduce the risk of complications, and regular monitoring throughout recovery. While treatment can take several months and may feel overwhelming at times, many dogs recover well and go on to live happy, healthy lives. Our compassionate team at Olive Branch will be with you every step of the way, offering guidance, support, and expert care throughout the process.
