What Is Heartworm?

Heartworm can affect both dogs and cats. The heartworm larvae can enter your pets body when it is bitten by an infected mosquito. The larvae then mature and migrate to your pets heart and lungs and reproduce.


Symptoms or signs in your pet may not appear until a year after infection, they include:

  • cough
  • difficulty breathing
  • reluctance to exercise
  • decreased appetite
  • weight loss
  • heart failure


A simple blood test performed by your veterinarian can diagnose heartworm in your pet. Heartworm can be treated but it is often complicated and involves long hospital stays for the animal. There is also a high risk of fatal complications and any damage to the heart and lungs cannot be reversed.



Luckily heartworm can be easily prevented! There are a range of worming medications available to administer to your pet all year round. It is best to speak to your veterinarian for advice on testing for heartworm and heartworm prevention.
