Canine Heartworm

Heartworms are found in the heart and the main blood vessels in the lungs of infected dogs and cats and are up to 30cm long. Infected dogs and cats may die unless heartworm infection is diagnosed and specifically treated, however the infection can be easily prevented.

Heartworms are spread by mosquitoes that bite infected animals and ingest tiny juvenile heartworms (microfilariae) in their meal of blood. These mature within the mosquito and can then be spread to other dogs and cats when the mosquito feeds again. The heartworm larvae then migrate from the mosquito bite wound, through the skin, to the heart and lungs of infected animals, where they mature.

All dogs and cats in mainland Australia are at risk of heartworm infection. They can be bitten by mosquitoes soon after birth, so protection should start at 6 weeks of age and continue throughout the animal's life.

Prevention of heartworm infection is straightforward. The best preventatives are given once a month, as a meaty chewable treat that your pets will actually enjoy eating. This chewable not only guards your pet's heart but can also provide control of roundworm and hookworm, the most significant intestinal parasites of puppies and kittens.

You can be sure that your pet is protected and because it is available only from your veterinarian, you know that it will be very effective.
