Pet owners across Australia are being urged to remain vigilant against paralysis ticks and Canine Ehrlichiosis as the cooler months set in. Despite the drop in temperature, new claims data from Pet Insurance Australia reveals that these dangerous parasites continue to pose a threat well beyond the summer season.

According to Pet Insurance Australia, incidents of paralysis ticks are still occurring throughout autumn and into early winter, surprising many pet owners who mistakenly believe that the risk diminishes with the end of summer. These ticks can cause severe illness in pets and can become life-threatening if not treated promptly.

Persistent Threat Despite Cooler Weather

Paralysis ticks thrive in environments abundant with vegetation, moisture, and wildlife hosts, allowing them to remain active even as temperatures begin to drop. Coastal regions of New South Wales and Queensland, in particular, are known hotspots for these ticks.

Nadia Crighton, spokesperson for Pet Insurance Australia, highlights a common misconception: “One of the biggest misconceptions we see each year is that paralysis ticks disappear once summer ends. But our claims data shows tick incidents continue through autumn and even into early winter, particularly when conditions remain mild and humid.”

Dogs that frequent bushland, parks, or even suburban gardens are at risk of encountering ticks during the cooler months. Pet owners are advised to continue preventive measures and regular checks to protect their pets.

A Growing Concern: Canine Ehrlichiosis

While paralysis ticks remain a significant seasonal risk, experts are also warning about Canine Ehrlichiosis, a serious tick-borne disease spreading across northern Australia. This disease is caused by the bacterium Ehrlichia canis, transmitted by the brown dog tick.

Dr. Karen Hedberg BVSc, Chair of the Dogs Australia Health and Wellbeing Committee, states, “This is a deadly disease, and all dog owners should be aware of this advancing threat.” The disease, which affects a dog’s immune and blood systems, is now considered endemic in parts of northern Australia, with cases reported in every state except Tasmania.

As climate conditions warm, experts warn that the distribution of these ticks could expand further south, increasing the risk of infection. Pet owners are encouraged to stay informed and maintain year-round tick prevention, especially when traveling through affected areas.

Understanding Tick Paralysis

Paralysis ticks inject a toxin that impacts a pet’s nervous system. Symptoms can initially appear mild but may rapidly escalate. Early signs include:

  • Weakness or wobbliness in the hind legs
  • Vomiting or gagging
  • Excessive drooling
  • Difficulty breathing
  • Lethargy

Nadia Crighton emphasizes the urgency of the situation: “Tick paralysis can escalate very quickly and often requires urgent veterinary care. Early detection is critical, which is why pet owners should continue performing regular tick checks even during the cooler months.”

Prevention: A Year-Round Necessity

Pet Insurance Australia is urging pet owners to remain proactive in using tick prevention products throughout autumn. Regular grooming and physical checks, particularly around the head, neck, and ears, are vital in identifying ticks early.

“Ticks are incredibly small and easy to miss, which is why prevention and routine checks are so important,” Crighton advises. “Remaining proactive can make all the difference when it comes to protecting your pet.”

While many associate ticks with the peak of summer, data suggests the risk period may extend longer than expected in some regions. Pet owners are encouraged to consult their veterinarians about tick prevention strategies suited to their local environment and their pet’s lifestyle.

“Our pets rely on us to protect them from hidden dangers,” Crighton concludes. “Staying aware that tick risk doesn’t simply disappear when the weather cools can help keep pets safe all year round.”
