Heartworm is an internal parasite that is spread by mosquitoes, so your dog doesn't even need to be in contact with other animals to become infected.

Heartworm has a complex life-cycle.

For heartworms to be infective, they must spend part of their life-cycle in a mosquito. Then a single bite from a carrier mosquito can infect your dog.

As the worms mature and grow in the heart, they can cause a physical blockage, as well as thickening of the heart and blood vessels.

Heartworm infection may eventually lead to signs of heart failure (such as a. reluctance to exercise, lethargy, coughing) and eventually death. Heartworm is present throughout most of Australia.

Thankfully, heartworm is easy to prevent and should form part of your dog's health care routine.

We have very effective preventative treatment options available, including

  • An injection given once a year (Proheart SR-12)
  • Spot-on treatments
  • Tablets

If your dog hasn't been on heartworm prevention, we strongly recommend a heartworm test prior to starting a prevention program.

Please call us to discuss the best heartworm prevention for your pet.
