Paralysis Tick Season in Australia: Symptoms, Emergency First Aid & Year-Round Prevention

14th Jul 2026

Found a tick on your dog, or noticed them suddenly stumbling? Knowing the paralysis tick symptoms to watch for could save your pet's life. Paralysis tick Australia cases result in thousands of vet emergency visits each year, and the toxin can turn a healthy pet critical within hours.

Here's what every pet owner in a tick-prone area needs to know.

At a Glance:

  • Paralysis ticks are found along Australia's east coast, from north Queensland down to eastern Victoria
  • Symptoms range from mild wobbliness to breathing failure and can escalate within hours
  • If you spot symptoms or find a tick, go to a vet immediately
  • Year-round paralysis tick prevention is the most effective protection, even outside peak season
  • Cats are also at risk, and many dog products are toxic to them

What Is the Paralysis Tick?

Ixodes holocyclus is the paralysis tick that Australia's dogs and cats are most at risk from. This small, eight-legged arachnid injects a neurotoxin (holocyclotoxin) while feeding on your pet. Unlike native wildlife, which have some immunity, dogs and cats are highly susceptible. A single tick can cause progressive paralysis, respiratory failure, and death if treatment isn't started quickly.

Paralysis ticks live in coastal bushland, long grass, and anywhere wildlife move through. They don't jump or fly; they drop or climb onto your pet as it brushes past vegetation.

When Is Paralysis Tick Season?

Historically, paralysis tick season runs from late winter through spring and into summer, roughly August to February, with peak activity in Queensland and coastal NSW. But vets are seeing cases year-round now, particularly in warmer northern regions.

The practical takeaway: if you live in or travel to a tick-prone area, treat your pet all year. Paralysis tick season is no longer a predictable window.

Paralysis Tick Symptoms: What to Watch For

Paralysis tick symptoms often start vague and progress fast. Early signs can appear two to three days after a tick attaches.

Early symptoms:

  • Lethargy, reduced appetite
  • Vomiting or gagging
  • Change in bark or meow (softer, hoarser)

As paralysis progresses:

  • Wobbliness or staggering, starting in the back legs
  • Reluctance to stand, move or jump
  • Difficulty swallowing, excessive drooling
  • Laboured or noisy breathing
  • Inability to blink (risks eye damage)
  • Complete collapse

These symptoms can escalate to respiratory failure within hours. If you notice any of the above, even just wobbliness, search your pet for ticks immediately and contact your vet.

Emergency First Aid: What to Do If You Find a Tick

  • Remove it. Use tweezers or a tick remover, gripping as close to the skin as possible. Pull firmly and steadily. Don't burn it or squeeze the body.
  • Keep the tick in a small container for species identification at the vet.
  • Keep your pet calm and still. Movement speeds toxin absorption.
  • Don't give food or water. Tick toxin impairs swallowing, raising the risk of aspiration.
  • Go to a vet immediately, even if the tick is removed and your pet seems okay. Symptoms can worsen for up to three days post-removal.

Paralysis Tick Prevention: Your Best Defence

Consistent paralysis tick prevention is the single most effective defence for pets in a risk area. Paralysis tick Australia cases show ticks can release toxins before any symptoms appear, making prevention far more valuable than reaction.

For dogs

Modern oral chews are the most reliable option. NexGard Spectra (monthly) and Bravecto for dogs (spot-on lasting up to 6 months, or 3-month chew) work systemically. Daily coat checks are still recommended alongside any prevention product you use.

For cats

Permethrin (found in many dog tick products) is highly toxic and must never be applied to them or used near them. Safe options include tick and flea treatment for cats, such as Bravecto for cats and Revolution Plus. Cats in coastal bush zones in Australia face paralysis tick risk, even if they're largely indoors.

Daily tick searches still matter

Run your fingers slowly through your pet's entire coat, nose to tail, inside ears, between toes, under the collar. Around 90% of ticks are found forward of the shoulders.
