Every year, many Australian dogs and cats are treated for tick paralysis, and some don’t survive. The Australian paralysis tick, Ixodes holocyclus, lives in backyards up and down the east coast. It can take a pet from a slightly wobbly walk to struggling to breathe in a matter of hours. Here’s what every pet owner needs to know: the warning signs, what to do, and how to stop ticks reaching your pet in the first place.

What Is Tick Paralysis?

The Australian paralysis tick injects a potent neurotoxin through its saliva while it feeds. Over several days, that toxin gradually shuts down the nerves that control movement, swallowing and, eventually, breathing. According to the MSD Veterinary Manual, Ixodes holocyclus causes the most severe form of tick paralysis anywhere in the world, with mortality of up to 10% in affected dogs. Cats are affected too.

The danger is that the early signs are easy to miss. A tick the size of a sesame seed can be hidden deep in your pet’s coat, and by the time symptoms are obvious, the toxin is already doing damage.

Where and When Are Pets Most at Risk?

Paralysis ticks are found along the eastern coast of Australia, and they thrive in the leaf litter, long grass and garden beds of ordinary suburban backyards, not just bushland. Pets that spend time outdoors or live near bush are at higher risk, and dogs are affected more often than cats.

Spring and summer bring the biggest surge in tick numbers, but in coastal and northern areas ticks can be found all year round. As our tick control team sees in Sydney gardens every week, ticks don’t follow a neat calendar. Eggs, larvae, nymphs and adults can all be present in a garden at any time of year.

Tick Paralysis Symptoms in Dogs and Cats

Veterinary sources list these as the key warning signs. If you notice any of them, treat it as an emergency:

• A change in voice: a softer or different-sounding bark or meow, or losing it altogether.
• Wobbly back legs: unsteadiness, swaying, or difficulty getting up or jumping.
• Gagging, coughing or retching, or bringing up food or water.
• Changes in breathing: rapid, laboured, noisy or grunting breaths.
• Drooling or difficulty swallowing.
• Dilated pupils or loss of movement in the face.
• Weakness spreading to the front legs, then an inability to stand.

In cats, the signs are often more subtle. Watch for a changed meow, unusual hiding, a wobbly gait or rapid breathing.

Why Every Hour Matters

Tick paralysis can progress frighteningly fast. In severe cases, death from respiratory failure can occur within one to two days of the first signs appearing. Removing the tick doesn’t immediately stop the disease, because toxin already in the body can keep causing symptoms to worsen for some time afterwards. Treatment with tick antiserum, given by a vet, is what neutralises the toxin.

What To Do If You Suspect Tick Paralysis

• Call your vet or nearest animal emergency centre straight away, even if the signs seem mild.
• Keep your pet calm, quiet and cool. Stress and heat make breathing harder.
• Don’t offer food or water. Swallowing may already be affected, and your pet could choke or inhale it.
• Take your pet in even if you’ve already found and removed a tick, because there may be more than one.

Daily Tick Checks: The Habit That Saves Lives

Run your fingertips slowly over your pet’s whole body every day during tick season, feeling for small lumps. Ticks favour the head, neck, ears, face and front legs, but check everywhere: between the toes, under the collar, around the lips, under the tail and inside the ears. Clipping long-haired pets’ coats in warmer months makes ticks much easier to find.

Pets Bring Ticks Home to the Whole Family

A tick that hitches a ride on your dog or cat doesn’t always stay there. Ticks can drop off onto bedding, couches and carpets, and from there they can find their way to the people in your home. For humans, the Australian paralysis tick carries its own serious risks, including tick anaphylaxis and mammalian meat allergy, which is now affecting a growing number of Australians.

That’s why prevention works best in layers: a vet-recommended tick preventative for your pet, daily tick checks, and a backyard with far fewer ticks in it to begin with.

Why Your Yard Is the Missing Layer of Protection

Most pet owners already spend money on tick collars, chews or spot-ons, and they should. But those products work after a tick has already climbed onto your pet. A professional garden treatment tackles the problem at its source, eliminating active ticks and continuing to kill new ones as they hatch, so far fewer ever reach your pet, your kids or you.

Pet owners often ask whether yard treatment is safe for their animals. The products TickSafe uses are water based and biodegradable, very low in toxicity to all mammals including people and household pets, and safe around chickens and birds. They’re registered with the Australian Pesticides and Veterinary Medicines Authority.

Frequently Asked Questions

What are the first signs of tick paralysis in a dog?

The earliest signs are often a change in the sound of your dog’s bark, wobbliness in the back legs, gagging or vomiting, and changes in breathing. Any of these warrants an immediate call to your vet.

Can cats get tick paralysis in Australia?

Yes. Cats are affected less often than dogs, but the paralysis tick is just as dangerous for them. Signs in cats can be subtle, such as a changed meow, a wobbly walk or rapid breathing.

If I remove the tick, will my pet be okay?

Not necessarily. Toxin already in your pet’s body can keep causing symptoms to worsen after the tick is removed, and there may be other ticks you haven’t found. Always see a vet if your pet shows any signs.

When is paralysis tick season?

Tick numbers surge in spring and summer, but in coastal and northern parts of Australia ticks can be found all year round, so year-round prevention is the safest approach.

Is TickSafe’s yard treatment safe for my dog or cat?

TickSafe uses water-based, biodegradable products that are very low in toxicity to mammals, including household pets, and are registered with the APVMA. See our safety information for full details.
