Dog tick paralysis
In areas where paralysis ticks occur, a tick's toxin can cause progressive weakness that is a life-threatening emergency. Early signs include a wobbly or weak back end, a changed or weak bark, vomiting or gagging, and heavy breathing, which can worsen over hours to full paralysis affecting breathing. If your dog shows these signs, especially after time outdoors in a tick area, call a veterinarian immediately. Search for and, if you can, remove any tick, but do not delay veterinary care to keep searching — the toxin keeps acting and dogs can deteriorate quickly.
Go to a vet now if
- A wobbly, weak back end progressing to the front, or collapse
- A changed, weak, or absent bark
- Vomiting, gagging, drooling, or laboured/heavy breathing
- A known tick, or time outdoors in a paralysis-tick area
Call a vet today if
- A single tick found on a bright dog with no weakness (remove it and monitor closely; call your vet)
What to tell the vet
- Whether you found a tick and removed it
- When signs started and how fast they are progressing
- Any weakness, changed bark, vomiting, or breathing trouble
- Recent outdoor or travel history
- Your dog's weight
- Conditions and medications
What not to do
- Do not delay the vet to keep searching for a tick — the toxin keeps acting
- Do not offer food or water if your dog is weak or gagging (risk of choking)
- Do not assume removing the tick ends the danger — signs can still worsen
What your vet may check
Your vet will look for ticks, assess weakness and breathing, and may provide anti-toxin where available plus supportive care, sometimes including help with breathing in severe cases. Careful monitoring is essential as signs can progress.
Recovery support after veterinary assessment
Recovery can take days and requires rest and careful nursing as your vet directs, including how to feed safely. Any supportive nutrition is used on veterinary advice.
