Myth 3: My dog always needs tick protection

I think the popularity of vet television shows might explain why this could be my most common question from dog owners:

Do Dogs In Adelaide Get Ticks?

Ticks are eight-legged blood-sucking parasites which attach to their host and engorge with blood. In Australia there are many tick species, mostly associated with a specific native host species, and a few imported ones. But there is one tick which looms large in the minds of pet owners- the paralysis tick, Ixodes holocyclus.

This guy is truly scary. He’s common near bushland and causes a progressive paralysis that eventually cause respiratory arrest and death. Click here for a paralysis tick map plus tick prevention tips for dogs and cats.

Are There Ticks In South Australia?

Though you may never see them, there are many species of ticks present in South Australia. Most are quite harmless, and only target certain species. The picture is of ticks removed from a dog who had come down from the north of the state. These are likely the Brown Dog Tick (no, that doesn’t mean they only infest brown dogs) and are only harmful in the transmission of blood parasites. The large ones are almost fully engorged with blood.

The Good News

Thankfully the one tick that every dog owner fears isn’t everywhere. The paralysis tick is not found anywhere near South Australia. The distribution is mostly to the east of the Great Dividing Range in Queensland, NSW and Victoria associated with its bandicoot host. The closest locations recorded have been the western suburbs of Melbourne. National media programs and articles made on the east coast often forget people actually live anywhere else in Australia!

But there is one very important thing to remember. If you travel to these places, you should get in touch with the local vets and ask them if you should be using prevention. It’s not uncommon for pet owners to accidentally expose their pets simply because they were not aware of the local danger. Then you can imagine the problems we have trying to make the diagnosis when back in a paralysis tick- free area.

Here’s a last thought for the weekend. Have you ever given a thought to the plight of endangered parasites? Every species on the planet is likely to have highly adapted and specialised internal and external parasites, protozoa, bacteria and viruses which have co-evolved with their host species. Now imagine what happens when a host species becomes extinct.

Should we shed a tear for the thousands of species which also die when this happens?
