Florida’s warm, humid climate creates the perfect environment for mosquitoes — and with them, a constant risk of heartworm disease for your pets. Unlike colder states where mosquito season ends in winter, Florida pet owners face heartworm exposure every single month of the year. At Pet Xpert Animal Clinic in Apopka, FL, we see firsthand what happens when prevention lapses — and it’s a situation no pet owner wants to face. Call (407) 886-7387 to discuss the right heartworm prevention plan for your dog or cat.
What Is Heartworm Disease?
Heartworm disease is a serious and potentially fatal condition caused by a parasitic worm called Dirofilaria immitis. It is transmitted through the bite of an infected mosquito. Once inside a pet’s body, heartworm larvae travel through the bloodstream and eventually settle in the heart, lungs, and associated blood vessels — where they can grow up to 12 inches in length and live for several years.
Dogs are natural hosts for heartworms, meaning the worms can mature, reproduce, and multiply inside them. Cats can also be infected, though heartworm disease in cats presents differently and can be even harder to detect and treat. According to the American Heartworm Society, heartworm disease has been diagnosed in all 50 states — but Florida remains one of the highest-risk regions in the country.
Signs of Heartworm Infection in Dogs
Early-stage heartworm infection in dogs often shows no symptoms at all, which makes routine testing critical. As the disease progresses, signs may include:
- Mild, persistent cough
- Fatigue after moderate activity
- Decreased appetite and weight loss
- Swollen belly due to fluid accumulation
- Difficulty breathing in advanced cases
By the time symptoms become obvious, the disease may already be causing significant damage to the heart and lungs. This is why early detection through annual wellness exams and routine heartworm testing is so important.
Heartworm Disease in Cats: A Different Picture
Cats are atypical hosts for heartworms, meaning most larvae don’t survive to adulthood. However, even immature worms can cause a condition called Heartworm Associated Respiratory Disease (HARD), which mimics feline asthma. Symptoms in cats may include coughing, wheezing, vomiting, and in some cases, sudden collapse. There is no FDA-approved treatment for heartworm in cats, which makes prevention the only option. Our team at Pet Xpert Animal Clinic can help you choose a cat-appropriate preventative to keep your feline companion safe.
Why Florida Is a High-Risk State
Florida’s subtropical climate supports year-round mosquito activity. Even in the cooler months of December and January, temperatures rarely drop low enough to kill mosquito populations entirely. Central Florida communities like Apopka, Winter Garden, and Ocoee experience extended warm seasons that give mosquitoes ample time to breed and transmit parasites. Outdoor pets, pets that spend time near standing water, and even indoor cats can be at risk.
Prevention Is Simple — and Highly Effective
The good news is that heartworm prevention is easy, affordable, and extremely effective when administered consistently. At Pet Xpert Animal Clinic, we carry a variety of heartworm and flea preventatives in oral and topical forms for both dogs and cats. Most preventatives work by eliminating heartworm larvae before they can mature — which is why monthly dosing without gaps is essential.
We also recommend annual heartworm testing for all dogs, even those on prevention. No medication is 100% effective if doses are missed or if the product is vomited before being absorbed. Testing catches any early infections before they progress.
What to Expect at Your Heartworm Prevention Appointment
When you bring your pet to Pet Xpert Animal Clinic for heartworm prevention, our veterinarian will review your pet’s health history, recommend an age- and weight-appropriate preventative, and may perform an in-house heartworm test using our on-site laboratory. Results are available the same day, and we’ll help you set up a reminder schedule to keep your pet protected month after month.
Don’t Wait — Protect Your Pet Today
Heartworm treatment for dogs is expensive, lengthy, and hard on the body. Prevention, by comparison, costs just a few dollars a month. If your pet isn’t currently on a heartworm preventative — or if it’s been more than a year since their last heartworm test — now is the time to act. Call Pet Xpert Animal Clinic at (407) 886-7387 or schedule an appointment online. Your pet’s heart health is worth it.
