Recognizing Heartworm Disease in Dogs and Cats

Heartworm disease can be difficult to detect in its early stages, as many pets show no visible signs until the infestation is advanced. In dogs, the most common symptoms include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and gradual weight loss. As the disease progresses, some dogs may develop a swollen abdomen due to fluid accumulation, or in severe cases, sudden collapse or difficulty breathing.

Cats, on the other hand, often display more subtle or varied symptoms. Signs to watch for are coughing or asthma-like attacks, intermittent vomiting, loss of appetite, weight loss, and lethargy. Unlike dogs, cats may show neurological symptoms or even sudden collapse or death without prior warning. Because cats are not the primary host for heartworms, even a small number of worms can cause significant health issues.

It’s important to remember that these symptoms can overlap with other common pet illnesses. If your pet is showing any of these signs or if you have concerns about their risk, scheduling an appointment with our veterinary professionals is the best step forward.

How Heartworm Disease Occurs: The Florida Connection

Heartworm disease is caused by a parasitic worm known as Dirofilaria immitis. The life cycle begins when a mosquito bites an infected animal, ingesting microscopic heartworm larvae. When the mosquito bites another dog or cat, the larvae are transferred and begin to mature in the new host. Over several months, these larvae travel through the bloodstream and settle in the heart, lungs, and associated blood vessels, eventually developing into adult worms that can grow up to a foot long.

Florida’s year-round warm temperatures and regular rainfall create a thriving environment for mosquitoes, making heartworm transmission a constant concern. Unlike regions with colder winters where mosquitoes die off, in Davenport and the surrounding communities, the risk never truly disappears. This is why our veterinarians recommend year-round prevention rather than seasonal approaches.

Additionally, both indoor and outdoor pets are vulnerable. Even if your cat or dog spends most of their time inside, mosquitoes can easily enter homes through open doors, windows, or during daily walks. The misconception that indoor pets are safe from heartworms puts many animals at unnecessary risk.

Professional Heartworm Treatment and What to Expect

If your pet is diagnosed with heartworm disease, our veterinary team at St. Charles Veterinary Hospital will develop a treatment plan tailored to their specific needs. For dogs, treatment typically involves a series of injections with a medication designed to kill adult heartworms, along with other supportive medications to reduce complications. The process can be lengthy, often spanning several months, and requires strict exercise restriction to prevent dangerous complications as the worms die off.

Additional therapies may include antibiotics to address bacteria released by dying worms, medications to kill immature larvae, and in severe cases, hospitalization or surgical removal of heartworms. Recovery can be challenging, and some dogs may experience long-term damage to the heart or lungs even after successful treatment.

In cats, the situation is more complex. There is currently no approved drug therapy for eliminating adult heartworms in cats, so treatment focuses on managing symptoms and supporting the cat’s respiratory and cardiovascular health. Some cats may spontaneously clear the infection, while others require long-term care to manage ongoing symptoms. Regular monitoring and supportive care from our veterinary professionals are essential for the best possible outcome.

It’s crucial to understand that heartworm treatment is far more difficult, risky, and expensive than prevention. Early detection through annual screening gives your pet the best chance for a positive prognosis and reduces the likelihood of severe complications.

Heartworm Prevention: Your Pet’s Best Defense

Consistent, year-round prevention is the most effective way to protect your dog or cat from heartworm disease in Davenport. Our veterinarians recommend starting puppies and kittens on a monthly preventive as early as possible and maintaining this protection throughout their lives. Preventive options include oral chewables, topical medications, and in some cases, injectable products that provide continuous coverage for several months.

Steps to effective prevention involve working with your veterinarian to select the right product for your pet’s species, age, weight, and lifestyle. It’s important to administer preventives according to schedule; missing even a single dose can leave your pet vulnerable to infection. Additionally, annual heartworm testing is strongly advised for all dogs, even those on regular preventives, to ensure early detection and prompt intervention if needed.

For cat owners, regular heartworm prevention is equally vital, especially since there is no approved treatment for infected cats. Our veterinary team can recommend safe, effective preventives tailored to your indoor or outdoor cat’s needs.

Other home care measures to reduce mosquito exposure include keeping screens in good repair, using pet-safe mosquito repellents around the home, and eliminating standing water where mosquitoes breed. While these steps help minimize risk, they should always be paired with veterinary-prescribed preventives for complete protection.

When to Seek Veterinary Care for Heartworm Concerns

Timely veterinary care makes all the difference when it comes to heartworm disease. If your pet displays any of the symptoms discussed earlier—such as coughing, fatigue, loss of appetite, or unexplained weight loss—it’s important to schedule an appointment for a thorough examination and testing. Even if your pet seems healthy, annual heartworm screening is an essential part of preventive care, especially in our mosquito-prone region.

February is an excellent month to review your pet’s heartworm prevention status and schedule their annual screening. This ensures that your pet is protected before the peak mosquito season arrives and helps catch any infections as early as possible. Our veterinary professionals are always available to answer your questions, review your pet’s history, and update their preventive care plan.
