Treating Heartworms In Dogs: What Every Pet Owner Should Know

Heartworm in dogs and/or cats and its treatment

As a pet owner, it is important to understand the risks of heartworms and the importance of treating and preventing them in dogs. Heartworm disease is a severe and potentially fatal condition caused by parasitic worms in infected animals' hearts and lungs. This article will discuss the causes, symptoms, and treatments for heartworm disease in dogs.

Causes Of Heartworm Disease

Heartworm disease is caused by a parasitic worm called Dirofilaria immitis. These worms are transmitted from one animal to another through the bite of an infected mosquito. Once inside a dog's body, the worms mature and reproduce, causing damage to the heart and lungs.

Symptoms Of Heartworm Disease

The symptoms of heartworm disease can vary depending on the severity of the infection. Some dogs may show no symptoms at all, while others may exhibit a range of symptoms, including:

  • Coughing
  • Lethargy
  • Difficulty breathing
  • Loss of appetite
  • Weight loss
  • Bulging chest
  • Collapse

If you notice any of these symptoms in your dog, it is important to contact your veterinarian as soon as possible.

Diagnosis Of Heartworm Disease

Diagnosis of heartworm disease involves a blood test to detect the presence of heartworms in a dog's bloodstream. If a dog tests positive for heartworms, additional tests may be performed to determine the severity of the infection and the best course of treatment.

Treatment Of Heartworm Disease

Treating heartworm disease in dogs can be a long and complicated process. The first step is stabilizing the dog's condition by addressing symptoms such as coughing or difficulty breathing. Once the dog is stable, the actual treatment for heartworms can begin.

The most common treatment for heartworm disease in dogs involves a series of injections of a medication called melarsomine. This medication is given in three separate doses, two days apart. The injections are administered into the muscles of the dog's back, and the dog is closely monitored for any adverse reactions.

During treatment, it is important to keep the dog calm and quiet to avoid any unnecessary strain on the heart and lungs. In addition, exercise and activity should be restricted to short walks on a leash.

Prevention Of Heartworm Disease

Prevention is the key to protecting your dog from heartworm disease. There are several preventive medications available that are effective in preventing heartworms from developing in dogs. These medications are available in different forms, including pills, topical solutions, and injections.

Working with your veterinarian to determine the best preventive medicine for your dog is important. When recommending a preventative medication, your veterinarian will consider your dog's age, breed, and overall health.

In addition to preventive medication, reducing your dog's exposure to mosquitoes is also important. This includes keeping your dog indoors during peak mosquito activity times and using mosquito repellent products.


Heartworm disease is a severe and potentially fatal condition in dogs. As a pet owner, it is important to take steps to prevent heartworms from developing in your dog and to seek veterinary care if your dog exhibits any symptoms of heartworm disease. By working closely with your veterinarian and following preventive measures, you can help keep your dog healthy and happy for years to come.
