Heartworm disease is caused by a parasite that is transmitted by mosquitoes. It occurs in many areas of Australia but is most common in NT, QLD, NSW and Northern WA. However, heartworm infected dogs are found as far south as Melbourne.

Once an infected mosquito has bitten, tiny larvae migrate under the dogs skin and undergo a maturation process, eventually ending up in the heart. The worms clog the heart and surrounding blood vessels eventually leading to heart failure, lung disease and death if left untreated. If caught early, heartworm can be treated but this is costly and there may be permanent damage to the dog’s heart and lungs.

The difficult thing with infected dogs is they do not show immediate signs of heartworm infection. By the time the symptoms occur the disease is advanced and serious. Signs include – coughing, weight loss, reluctance to exercise and lack of energy. If your dog shows any of these symptoms, please see your vet.

This is a definite case of prevention being better than cure and there are many preventatives available on the market, including tablets and injections, but probably the easiest of all is a product called Advocate. Available from your veterinarian, this is a drop product that you simply squeeze onto the back of the neck. You apply once a month and Advocate also protects against fleas and internal parasites. Your vet can help you choose which is the best product for you.

It is possible for cats to develop heartworm disease (although this is not as common)- Advocate given once a month will offer your puss all the protection he/she needs.

If you have missed your pet’s tablets or other preventative, talk to your vet about what to do. Also, if you are traveling with your pet or unsure about the heartworm risk in your area, your vet can advise you. A simple blood test can be carried out in the clinic will make sure your pet is not infected. You can then start on a preventative program to ensure peace of mind for all the family.
