Dog Heartworm Disease in Palmetto Bay, FL
For South Florida pet owners, the threat of heartworm disease isn’t a seasonal concern—it is an everyday reality. Our beautiful, lush environment in Palmetto Bay, complete with coastal breezes, backyard canals, and warm tropical temperatures, also happens to be the absolute perfect breeding ground for mosquitoes. And where there are mosquitoes, there is heartworm.
At The Falls Animal Clinic, we want to help you protect your dog from this entirely preventable, yet potentially fatal, disease. Led by Dr. Doly Baquero, who brings over 37 years of clinical veterinary experience to our community, we take a proactive, compassionate, and cost-conscious approach to heartworm management. We are a privately-owned clinic, which means we focus on what is medically best for your dog and your family budget—not corporate-mandated sales quotas.
What is Heartworm Disease & Why is Palmetto Bay High-Risk?
Heartworm disease is a serious and progressive condition caused by parasitic worms called Dirofilaria immitis. These worms live inside the heart, lungs, and associated blood vessels of infected dogs. Over time, they grow up to a foot in length, causing severe damage to the lungs, clogging the heart valves, and restricting blood flow to vital organs.
The South Florida Connection
Unlike other regions of the country that experience a hard winter freeze to naturally pause the mosquito lifecycle, Miami-Dade county has a year-round mosquito season.
Whether your dog spends their afternoons walking around the Deering Estate, playing in your backyard, or just stepping outside for a quick potty break, they are at risk. Because mosquitoes can easily slip indoors through open doors or tiny tears in window screens, even strictly indoor dogs require continuous, year-round protection.
How Do Dogs Catch Heartworms?
A dog cannot catch heartworms directly from another dog. The disease can only be transmitted through the bite of an infected mosquito.
THE HEARTWORM TRANSMISSION CYCLE
When an infected mosquito bites a dog, it leaves behind microscopic, infective larvae. These larvae migrate through the dog’s tissues, eventually entering the bloodstream and settling in the heart and lungs, where they mature into adult, foot-long worms in about six to seven months.
Recognizing the Signs of Heartworm Disease
In its earliest stages, heartworm disease is completely silent. Your dog may look, act, and feel 100% healthy while the worms are slowly maturing inside their cardiovascular system. This is why annual testing is so critical.
As the disease progresses and the worm burden increases, you may begin to notice the following symptoms:
- Mild Stage: A persistent, mild, and dry cough—especially after physical exertion.
- Moderate Stage: Uncharacteristic lethargy, reluctance to exercise, and tiring quickly during normal walks.
- Severe Stage: A decreased appetite, noticeable weight loss, a swollen or "pot-bellied" appearance (caused by fluid accumulation in the abdomen), and labored breathing.
- Emergency (Caval Syndrome): A sudden block of blood flow to the heart, leading to pale gums, dark coffee-colored urine, and collapse. This is a life-threatening emergency requiring immediate surgical intervention.
Diagnostics: Why We Require an Annual Heartworm Test
We perform a highly accurate, quick in-house blood test (antigen test) to screen for the presence of adult female heartworms.
Why can’t I just buy preventative without a test?
Giving heartworm preventative to a dog that already has active, mature heartworms can be incredibly dangerous. The preventative medication can cause a rapid die-off of microscopic baby worms (microfilariae) in the bloodstream, triggering a severe, life-threatening shock-like allergic reaction.
Additionally, no preventative is 100% effective. If your dog spit out a chewable tablet when you weren’t looking, or if a topical dose didn’t absorb completely, an annual test ensures we catch any accidental infections early before irreversible heart and lung damage occurs.
The 6-Month Window for Puppies
Because it takes about six to seven months for heartworms to mature to the point where they can be detected on a test, puppies under six months of age do not need to be tested before starting prevention. However, they must be started on a preventative immediately to protect them as they grow.
Prevention vs. Treatment: A Clear Comparison
At The Falls Animal Clinic, we believe in being entirely transparent about the medical and financial realities of pet care. When it comes to heartworms, prevention is always vastly superior to treatment.
| Feature | Year-Round Prevention | Active Heartworm Treatment |
| Administration | Easy monthly chewables, topical applications, or twice-yearly injections. | A series of deep, painful intramuscular injections in the lower back. |
| Dog’s Lifestyle | Normal, active, and happy. | Strict crate rest for several months (elevated heart rates can cause dead worms to clog pulmonary arteries). |
| Health Impact | Safe and gentle on the body. | Extremely stressful; can cause severe respiratory and cardiovascular complications. |
| Cost | Affordable and cost-conscious (spread out over the year). | Highly expensive (often costing thousands of dollars for diagnostics, medications, and hospitalization). |
