What Is Heartworm In Dogs? Heartworm Diagnosis and Treatment Methods? How to Prevent Heartworm?


Heartworm is a disease caused by a parasite known in veterinary medicine as Dirofilaria immitis. This parasite enters the bloodstream of dogs, usually through the bite of mosquitoes. The larvae then develop into mature worms in the dog's heart and lungs.

Heartworm is a disease that is especially common in hot and humid climates. Dogs living in areas where mosquitoes are present are at risk. This parasite targets the dog's heart, lungs and circulatory systems to provide the best living environment in the body.

Symptoms of a heartworm infection can differ from dog to dog. However, some common symptoms may include:

  • Cough may increase, especially after exercise or while lying down.

  • Difficulty or difficulty breathing.

  • Weakness and fatigue.

  • Loss of appetite and weight loss.

  • Abdominal swelling.

  • Signs of edema (fluid accumulation) can be seen especially in the legs or abdomen.

Heartworm is a serious disease that requires a veterinarian to be consulted for diagnosis and treatment. The veterinarian can diagnose the infection through methods such as blood tests, X-ray imaging or ultrasound.

Treatment is usually done with medications. Giving the dog a special heartworm preventive medication can prevent the infection from progressing and the formation of more worms. In advanced cases, surgical intervention may be required.

Heartworm is a disease that can cause serious health problems in dogs. Therefore, it is important to take preventive measures to protect your dog from mosquitoes. This may consist of not taking your dog out in mosquito-infested areas, using appropriate mosquito repellent, and regularly using heartworm preventive medications recommended by your vet.

How to Diagnose Heartworm?

The diagnosis of heartworm can be made by veterinarians using a variety of methods. Below you can find commonly used diagnostic methods:

  • Blood Tests: Veterinarians can perform blood tests to detect heartworm-specific antibodies or parasite DNA in the dog's blood. These tests are usually performed using techniques such as ELISA or PCR.

  • X-Ray Imaging: X-ray allows the dog's chest area to be visualized. In dogs with heartworm infections, mature worms can form distinctive shapes in the heart and lungs as they pass through the pulmonary vessels. X-ray imaging is a diagnostic method used to detect the presence of worms.

  • Echocardiography: Echocardiography, or ultrasound, provides detailed imaging of the dog's heart and lungs. With this method, changes such as enlargement of heart chambers or vessels, impaired blood flow or visualization of worms can be detected due to heartworm infection.

Your veterinarian will select appropriate diagnostic methods based on your dog's symptoms, medical history, and physical examination findings. In most cases, a more precise result is obtained by using more than one diagnostic method together. For this reason, it is important to consult a veterinarian and take your dog for regular checkups.

How to Treat Heartworm?

Heartworm treatment is a veterinarian-administered process that varies depending on the dog's condition. Generally, one or more of the following treatment methods are used:

  • Administration of Medication: The veterinarian will prescribe specific medications to treat heartworm infection and ensure the worms are killed. These drugs help kill the worms and remove them from the body. The treatment process can usually take several months and can be repeated regularly depending on a specific drug protocol.

  • Steroid and Supportive Therapy: To improve the dog's condition and relieve symptoms during heartworm treatment, the veterinarian may recommend supportive treatments such as anti-inflammatory drugs or steroids. These treatments can help manage the dog's shortness of breath, edema, or other symptoms.

  • Surgical Intervention: In advanced cases, dogs with large accumulations of worms may require surgical intervention. This intervention can be used to remove or remove worms from the heart and lung vessels. Surgery is usually a risky option and is performed in line with the evaluation and recommendation of the veterinarian.

When treating heartworm, it is important that the dog has regular veterinary check-ups, medication is given correctly, and certain instructions are followed. In addition, it is recommended to use regular heartworm preventive drugs after treatment.

Remember that heartworm treatment is a complex process and your veterinarian will determine the most appropriate treatment plan. Therefore, it is important to take your dog to a veterinarian as soon as possible.

How to Prevent Heartworm?

You can take the following precautions to prevent heartworm infection:

  • Heartworm Preventive Medicines: Regularly using heartworm preventive medicines recommended by your veterinarian is the most effective prevention method. These drugs prevent infection by killing the worm larvae that enter the dog's body.

  • Controlling Mosquitoes: Heartworm is transmitted by mosquito bites. You can use mosquito repellent products indoors and outdoors to control mosquitoes. In addition, it may be useful to take care not to wander around the areas where your dog goes outside during peak mosquito hours.

  • Keeping the Dog Indoors: Keeping dogs that live in mosquito-infested areas indoors as much as possible can reduce the risk of infection. It is important to avoid going outside, especially during the most active hours of mosquitoes.

  • Keeping the Environment Clean and Orderly: It is important to keep the environment clean and tidy to prevent mosquitoes from breeding. Emptying puddles in pots and clearing litter and stagnant water areas reduce mosquito breeding grounds.

  • Regular Veterinary Checkups: Taking your dog to veterinary checkups regularly is important for monitoring its health and early detection. Your veterinarian can assess your dog's risk for heartworm infection and guide you on preventive measures.

These precautions will help you reduce your risk of heartworm infection. To protect your dog, it is important to follow your veterinarian's recommendations and regularly use preventative medications.
