What Exactly Are Heartworms

At Alexander At The Park Veterinary Hospital in Durham, NC, we are dedicated to providing clear, factual information about pet health issues, including heartworms. Heartworms are parasitic worms that primarily affect dogs but can also infect cats and other animals. Understanding what heartworms are and how they affect your pet is essential for effective prevention and treatment.

Understanding Heartworms

Heartworms are long, thin parasitic worms that live in the heart, lungs, and associated blood vessels of infected animals. These parasites are transmitted through the bite of an infected mosquito. Once inside the animal, heartworm larvae develop into adult worms over several months, eventually causing damage to the cardiovascular and respiratory systems. Although heartworms are most common in dogs, they can also infect other animals, leading to serious health issues if left untreated.

How Heartworms Infect Your Pet

Mosquitoes play a key role in spreading heartworms. When a mosquito bites an infected animal, it picks up heartworm larvae. Later, when that mosquito bites another animal, it transmits the larvae. Over time, the larvae mature into adult heartworms, which can grow several inches in length. These adult worms lodge in the heart and the pulmonary arteries, interfering with normal blood flow and causing strain on the heart.

Signs and Symptoms of Heartworm Disease

Early stages of heartworm infection may not show obvious symptoms, which is why regular veterinary check-ups are important. As the disease progresses, symptoms in dogs can include coughing, fatigue, difficulty breathing, and weight loss. In severe cases, heartworm disease can lead to heart failure. Early detection through routine examinations is key to effective treatment and a better prognosis for your pet.

Prevention and Treatment

Preventing heartworm disease is much simpler and more effective than treating an established infection. Preventative medications, available in both oral and topical forms, are highly effective when administered consistently. Our veterinarian recommends that pets receive heartworm prevention year-round, as mosquitoes can be active even during cooler months. For pets diagnosed with heartworm infection, treatment options include a series of injections to eliminate the adult worms, though prevention remains the best strategy.

The Role of Regular Exams

Regular veterinary exams are crucial in catching heartworm disease early. During a wellness exam, our veterinarian conducts tests that can detect the presence of heartworms before symptoms develop. This proactive approach allows for timely intervention and better management of the disease, ensuring your pet maintains a high quality of life.
