Heartworm is becoming more common in Australia again, and most infected dogs show no signs. Richard L’Estrange from Zoetis explains how it spreads, how to test for it and how to interpret the results, and why prevention matters.
Includes the full recording (37 minutes) and a quiz. Pass the quiz to receive a certificate worth 1 AVNAT point.
Only about one in five heartworm-positive dogs in Australia shows clinical signs, so if you’re not testing, you’re not finding it. Heartworm is re-emerging, and it is no longer just a Queensland problem.
Richard L’Estrange from Zoetis gives you an Australian update on heartworm: how big the worms grow and how long they live, the wildlife reservoirs, why heartworm is a zoonosis, and the damage the worms do to the pulmonary arteries well before a test can find them. You’ll walk through the full life cycle, from microfilariae in the mosquito to adult worms in the dog, and see exactly which stage preventatives target and why a late monthly dose can fail.
You’ll also learn why heartworm is spreading, why every dog should be tested, how antigen tests and microfilaria tests work and how to interpret the four possible combinations of results, the role of radiography and ultrasound, and why treatment is so difficult that prevention is the only sensible approach.
