Paralysis Tick on Your Dog: What to Do Now

If your dog is weak, wobbly, gagging, vomiting, coughing, or breathing differently after tick exposure, treat it as an emergency and call a vet now.

Paralysis ticks are most common along Australia's east coast, and symptoms can keep worsening even after the tick is removed.

The Short Answer: Call First, Then Act

If you found a tick on your dog in a paralysis-tick area, the safest first move is to call your vet or nearest emergency vet. If your dog has any symptoms — even mild wobbliness or a changed bark — call from the car and go in.¹

Paralysis ticks inject a neurotoxin while feeding. In Australia, Ixodes holocyclus is the major concern and causes a more severe form of tick paralysis than many overseas tick species.² The Animal Poisons Helpline notes that signs are often delayed 3-5 days from when feeding begins, which means a dog can look normal while the toxin is already building.¹

Use this quick decision table:

What you see	What to do
Tick found, dog normal	Remove the tick if you can do it promptly, keep the tick, then call your vet for advice
Tick found plus changed bark, vomiting, weakness, wobbliness, coughing, gagging, or breathing change	Emergency vet now
No tick found, but the dog has sudden hind-leg weakness in a tick area	Emergency vet now — the tick may have fallen off or be hidden
Dog is breathing hard, noisy, or open-mouthed	Drive now and call ahead

What to Do in the Next 5 Minutes

1. Keep your dog calm and still. Stress and exertion can worsen breathing difficulty in affected dogs. Carry small dogs if you can. Keep larger dogs walking as little as possible.

2. If you can see the tick, remove it promptly. Use a tick-removal tool or fine tweezers, grasping close to the skin. Pull steadily. Do not burn the tick, paint it with chemicals, or squeeze the body hard while trying to remove it.³

3. Save the tick. Put it in a sealed bag or container. It may help the vet identify what you removed.

4. Search for more ticks. One tick does not rule out another. Search with your fingertips, against the direction of fur growth, feeling for small lumps. Check the head, neck, ears, lips, mouth edges, collar line, armpits, groin, between toes, and under the tail.

5. Call a vet even if symptoms seem mild. In Australian tick paralysis, signs can keep progressing after removal; Merck notes that dogs may worsen for about 24 hours after tick removal and treatment before improving.²

If your dog is gagging, coughing, regurgitating, or struggling to swallow, do not offer food or water while you are waiting for veterinary advice. Aspiration is a real risk in dogs with throat or swallowing weakness.

Symptoms That Mean Emergency Vet Now

Early signs can be subtle, especially if you have never seen tick paralysis before. Owners often describe the first clue as "not quite right".

Watch for:

• Change in bark, softer bark, or loss of voice
• Weakness or wobbliness in the back legs
• Sitting down repeatedly or struggling with stairs
• Vomiting, retching, gagging, or coughing
• Drooling or trouble swallowing
• Loss of appetite
• Fast, noisy, or laboured breathing
• Collapse or inability to stand

Animal Poisons Helpline describes the classic progression as weakness in the rear legs, then worsening paralysis, coughing, laboured breathing, and difficulty swallowing.¹ MSD Veterinary Manual lists changed voice, hind-leg incoordination, breathing changes, gagging or coughing, vomiting, and dilated pupils among early signs in dogs.⁴

Breathing changes are the line you do not negotiate with. If breathing looks harder than usual, sounds noisy, or your dog cannot settle, go to an emergency vet immediately.

Where to Search: Ticks Hide in Boring Places

Paralysis ticks often attach where dogs cannot easily scratch them off. Merck notes that most ticks are found around the head and neck, but they can be anywhere on the body.²

A proper tick search is done by feel, not just by sight — especially on thick-coated dogs.

Use a slow fingertip search:

• Nose, lips, gums, and mouth edges
• Around and inside ears
• Eyelids and face
• Under the collar
• Neck, shoulders, and chest
• Armpits and front legs
• Between every toe
• Groin and belly
• Under the tail

Animal Poisons Helpline recommends tick searches 3-4 times per week in risk areas, with particular attention to the head, neck, front legs, ears, lips, mouth, nose, and toes.¹ In peak season or after bush, scrub, beach-track, or long-grass exposure, daily checks are more sensible.

What the Vet May Do

Tick paralysis treatment is not just "remove the tick and wait". Australian cases can need active veterinary care.

Depending on severity, your vet may:

• Repeat a full tick search and clip fur if needed
• Give tick antiserum to bind circulating toxin
• Provide oxygen support
• Give anti-nausea medication or sedation
• Monitor breathing, temperature, hydration, and swallowing
• Hospitalise your dog for observation, especially if breathing or swallowing is affected
• Use intensive care and ventilation in severe cases

The 2024 Australian Paralysis Tick Advisory Panel guidelines include separate protocols for dogs with no clinical signs but evidence of a tick or tick crater, and dogs with clinical signs with or without a tick found.⁵ That distinction matters: a dog with symptoms needs a different level of urgency from a dog who is bright and normal after one tick was removed.

When to Skip Home Care Entirely

Go straight to an emergency vet if any of these apply:

• Your dog is weak, wobbly, collapsed, or cannot stand
• Breathing is noisy, fast, laboured, or open-mouthed
• Your dog is gagging, coughing, vomiting repeatedly, or cannot swallow
• Your dog is a puppy, senior, pregnant, brachycephalic, or has heart/lung disease
• You live in or recently visited a known paralysis-tick area and symptoms fit, even if you cannot find a tick
• You removed a large grey tick and your dog is even slightly abnormal

Do not wait for paralysis to become obvious. The earlier signs — changed voice, back-leg weakness, vomiting, and breathing changes — are the useful warning lights.

Honest Limits: What AI and Home Checks Cannot Tell You

Home checks can help you decide whether the situation is suspicious. They cannot tell you how much toxin has been absorbed, whether there is another hidden tick, or whether your dog's breathing and swallowing are about to worsen.

PetCare AI can help you organise the story quickly: where you live, whether a tick was found, what symptoms are present, breathing effort, timing, and risk factors. But if your dog has signs of tick paralysis, AI is not a substitute for a vet. The right answer is professional care, fast.

Prevention: The Part That Saves the Most Dogs

Paralysis ticks are found mostly along Australia's east coast and are most active in spring and early summer, although risk varies by local climate and season.¹ Dogs can pick them up in bushland, coastal scrub, long grass, gardens visited by wildlife, and even from ticks carried indoors on clothing or gear.¹

Prevention is layered:

• Ask your vet which tick preventative is appropriate for your dog and your local risk area
• Use preventatives exactly on schedule; late doses create gaps
• Do fingertip tick searches during risk season, especially after walks
• Keep lawns short, trim shrubs, and reduce dense garden edges where pets rest
• Avoid known tick-heavy tracks during peak risk periods
• Check dogs before bedtime after bush, beach-track, or long-grass exposure
• Save your regular vet and nearest 24-hour emergency vet in your phone

No preventative is a permission slip to stop checking. The best system is both: an effective product plus human hands on the dog, often.
