Paralysis tick season in NSW usually increases during spring and summer, when warmer weather creates ideal conditions for tick activity. Dogs and cats can be exposed even in backyards, gardens and local walking areas.

The paralysis tick (Ixodes holocyclus) is one of the biggest seasonal health risks for pets in eastern Australia, particularly across NSW. These tiny parasites can cause serious illness by releasing a toxin that affects the nervous system, and in severe cases, paralysis ticks can be life-threatening without urgent veterinary treatment.

Our veterinarians regularly see pets affected by parasite-related illnesses, including paralysis ticks across NSW. Understanding how paralysis ticks spread, recognising early warning signs and using reliable dog tick prevention and cat tick protection can help keep your pets safe throughout the warmer months.

When Is Paralysis Tick Season in NSW?

While paralysis ticks can be active throughout the year, the risk increases significantly during spring and warmer months. Tick activity in NSW typically starts increasing from August, with the highest risk period occurring from September to December. Activity can continue through January, February and March, with ticks remaining a concern outside these months depending on local weather conditions, rainfall and habitat. Paralysis ticks are particularly common along the eastern coast of Australia, including many parts of NSW. Pets living near bushland, coastal vegetation, parks and rural properties may have a higher risk of exposure. This means pets do not need to go on a major adventure to be exposed. A walk through a local reserve, playing in the backyard or visiting a friend’s property can be enough for a tick to attach. Regular tick checks and preventative treatments are essential during peak tick seasons, but knowing how to safely identify and remove a tick from your dog can also help reduce the risk of tick-related health problems.

Why Paralysis Ticks Are Dangerous for Dogs and Cats

Unlike some common parasites that cause irritation or discomfort, paralysis tick toxin affects the nervous system by interfering with communication between nerves and muscles. Once attached, a tick may slowly release toxins into your pet’s bloodstream. The longer it remains attached, without treatment, affected pets can develop worsening weakness and respiratory complications.

Signs of tick paralysis can include:

  • Weakness or difficulty walking
  • Wobbly movement, especially in the back legs
  • Loss of coordination
  • Change in bark or meow
  • Excessive drooling
  • Vomiting or gagging
  • Difficulty breathing
  • Collapse

If you notice any of these signs, your pet should be seen by a veterinarian as soon as possible. Tick paralysis can progress quickly, and early treatment often makes a significant difference.

Dog Tick Prevention for a Safer Tick Season

Reliable dog tick prevention is one of the most important steps you can take during paralysis tick season. Many pet owners assume a tick collar, treatment or medication used occasionally is enough, but the safest option depends on your dog’s age, weight, health, lifestyle and exposure risk. Avoid recommending specific brands unless medically appropriate.

Along with preventative treatments, daily tick checks are still valuable, especially after walks or outdoor activities. Keeping your dog up to date with routine veterinary care, including recommended dog vaccinations, can also support their overall health and help ensure they are protected throughout every stage of life.

Check common tick hiding areas, including:

  • Around the ears
  • Under the collar
  • Between the toes
  • Around the face and eyes
  • Inside the lips and gums
  • Under the front legs
  • Between the back legs

 

Puppy Tick Prevention Tips for a Safe Spring

Puppies love exploring new environments, but spring also brings increased tick activity across many parts of NSW. Because young puppies have developing immune systems and smaller body sizes, choosing the right tick prevention method is an important part of keeping them safe during outdoor adventures.

Young puppies can be more vulnerable than adult dogs because their bodies are still developing. Not all tick treatments are suitable for puppies. Some products are designed only for dogs above a certain age or weight, which is why choosing prevention with veterinary guidance is important.

Teach your puppy to enjoy tick checks

  1. Start handling your puppy early to build comfort with health checks.
  2. Gently touch their ears, paws, neck and body to make tick checks easier.
  3. Regular practice helps reduce stress during future inspections.

Indoor Cats Can Still Be at Risk From Paralysis Ticks

Many cat owners assume their indoor cat is protected from ticks because they rarely go outside. However, paralysis ticks can still find their way into homes and pose a serious health risk, especially during paralysis tick season in NSW.

Even cats that live completely indoors can still be exposed to paralysis ticks. Ticks are excellent hitchhikers and can accidentally enter your home through:

  • Clothing after outdoor activities
  • Shoes and bags brought inside
  • Other pets that spend time outdoors
  • Outdoor furniture, bedding or garden items
  • Open doors, windows or balconies

Once inside, a tick may attach to your cat while they are resting, sleeping or exploring areas around the home. Keeping your cat’s vaccinations up to date, along with regular parasite prevention and health checks, can help support their overall wellbeing and ensure they are protected against preventable health risks.

How to Check Your Pet for Paralysis Ticks

A thorough tick check should become part of your routine during paralysis tick season. Run your fingers slowly over your pet’s entire body, feeling for small lumps or bumps. Ticks can vary in size, so do not rely only on visible signs. Use your hands first, then look closely through your pet’s fur, especially around common hiding areas.

If you find a tick:

  • Remove it carefully using a tick removal tool if you are confident doing so.
  • Avoid squeezing the tick’s body, as this may increase toxin exposure.
  • Contact your veterinarian for advice, especially if your pet is showing any symptoms.

 

Protecting Your Pet During Paralysis Tick Season

Paralysis ticks are a serious seasonal threat for dogs and cats across NSW because their toxin can cause progressive weakness, breathing difficulties and potentially life-threatening illness if treatment is delayed.

Regular tick checks, appropriate preventative treatments and knowing the early warning signs of tick paralysis are some of the most effective ways to protect your dog or cat during the warmer months.

Keeping your pet safe during paralysis tick season starts with preparation before tick activity increases. A few simple steps can help your pet enjoy a safer and healthier spring.
