Detecting heartworm can be difficult as symptoms often don’t show until the condition is advanced. Tests performed by your veterinarian can confirm the presence of heartworm.

However, it’s important to look out for outward symptoms such as intolerance to exercise, soft coughing, weight loss, and visible pulsation of the veins in the neck. Other symptoms may include fainting or collapsing, fluid retention in the abdominal cavity, weakness, severe lethargy, blood-tinged phlegm, jaundice, anemia, and even death.

If your dog displays any of these symptoms, it’s essential to take them to the vet as soon as possible.


Preventing heartworm is affordable and easy. Most heartworm medication for dogs also protects against other parasites such as roundworm or hookworm. Year-round protection is recommended as heartworm transmission is a year-long threat in many countries. Regular preventative action is the only way to ensure your dog’s protection against heartworm.

Common Ingredients Used In Heartworm Medicine For Dogs:

There are several ingredients used in heartworm medication for dogs. Ivermectin, Milbemycin, and Moxidectin are commonly used antiparasitic drugs that protect against heartworms.

Heartgard Plus, Sentinel, and Proheart are some of the most commonly used heartworm medicines for dogs that contain these ingredients.


If heartworm is detected, treatment should begin immediately. The most effective initial treatment is to stop your dog’s exercise routine. A sedentary dog is less likely to suffer complications caused by the presence of heartworms.

One of the most common treatments for heartworm is to kill off adult worms using an arsenic-based drug called Melarsomine. The use of Melarsomine is dangerous and should only be administered by a skilled veterinarian. Inflammation of body tissues can often occur, and the prescription of aspirin may help inhibit blood clots from occurring. Again, you vet will be able to advise.

In Summary

Heartworm is a serious condition that can be fatal if left untreated. Regular preventative action is the best way to ensure your dog’s protection against heartworm.

If you suspect your dog has heartworm or displays any of the symptoms mentioned above, it’s important to take them to the vet as soon as possible. With proper care and attention, you can help ensure your four-legged friend stays healthy and happy for years to come.
