Paralysis Ticks in Northern NSW: What Every Pet Owner Needs to Know
Q: What are the signs that my pet is suffering from tick paralysis?
- Early Warning Signs: A subtle change in voice (a softer bark or meow), coughing, grunting, gagging, vomiting, or loss of appetite.
- Progressive Paralysis: Weakness or wobbliness in the hind legs, progressing to difficulty standing, walking, or full paralysis of all four legs.
- Respiratory Distress: Laboured or rapid breathing, grunting on exhalation, and abdominal heaving.
- Other Symptoms: Pupil dilation or an inability to blink.
Q: How quickly do paralysis ticks affect cats and dogs?
- Rapid Progression: Clinical signs typically appear 3 to 4 days after the tick attaches. However, once symptoms begin, pets can deteriorate extremely rapidly within hours.
- Life-Threatening Emergency: Without immediate treatment, tick paralysis can lead to complete respiratory failure and can be fatal within 24 hours of symptoms appearing.
Q: What should I do if I notice signs or find a tick on my pet?
- Remove the Tick Immediately: Use a tick removal tool, tweezers, or fingers to grasp the tick close to the skin and pull with a firm, steady twist-and-pluck motion. Save the tick in a container for identification.
- Seek Immediate Veterinary Attention: Contact King Street Veterinary Hospital right away.
- Withhold Food and Water: Paralysis affects the muscles used for swallowing, creating a high risk of choking or aspiration pneumonia.
- Keep Your Pet Calm and Cool: Restrict activity and avoid excitement or excess heat, as stress severely worsens breathing difficulties.
Q: I live in town—will my pet still get ticks?
- Yes! Paralysis ticks (Ixodes holocyclus) are brought into suburban yards and gardens by native wildlife like possums, bandicoots, wallabies, and birds. Even pets living strictly in town or residential backyards are at risk in Northern NSW.
Q: How do I prevent ticks from affecting my cat or dog?
- Year-Round Preventatives: Use a reliable, veterinarian-recommended preventative year-round (e.g., NexGard SPECTRA or Bravecto for dogs, and species-specific options for cats). Note: Never use dog tick products on cats as they can be fatal.
- Daily Physical Searches: Perform daily “finger-walking” searches over your pet’s entire body, focusing on the head, neck, ears, lips, toes, and under the collar.
- Yard Management: Keep grass short, clear leaf litter, and restrict access to dense bushland.
What do paralysis ticks look like, and how are they different from bush and cattle ticks?
- Paralysis Ticks (Ixodes holocyclus): Oval-shaped, light grey to white/grey when engorged (flat and greyish-brown when unengorged). Their legs are concentrated near the front of the body around the head parts. The first and fourth pairs of legs are dark orange-brown, while the middle two pairs are distinctly lighter/pale. Crucially, they secrete a potent neurotoxin that causes life-threatening paralysis.
- Bush Ticks (Haemaphysalis longicornis): Reddish-brown to dark brown in color. All 8 legs are uniformly dark brown and evenly spaced along the sides of the body (not clustered at the front). They do not secrete paralysis toxin, though heavy burdens can cause irritation or anemia.
- Cattle Ticks (Rhipicephalus microplus): Have pale yellow to light cream-colored legs that are short and evenly spaced along the sides of the body. They are typically found on livestock and in pastures, and do not cause tick paralysis.
Q: What is the point of paralysis ticks in nature?
In Australia’s ecosystem, ticks play a ecological role as parasites of native wildlife (such as bandicoots and possums), which have developed natural tolerance over generations. However, domestic pets are not natural hosts and lack immunity, making the neurotoxin in the tick’s saliva deadly to dogs and cats.
If you think your pet is showing signs keep them calm and get medical attention immediately.
