Tick paralysis is a rapidly reversible but potentially fatal condition caused by neurotoxins in tick saliva, requiring prompt tick removal and sometimes intensive supportive care.
Tick paralysis causes terrifying progressive weakness in affected dogs - owners often describe coming home to find a dog unable to stand that was walking normally hours earlier. Respiratory paralysis is the life-threatening endpoint that makes rapid recognition essential. The reversibility of most North American cases with prompt tick removal represents a welfare opportunity - if caught early, recovery is complete. Australian tick cases require intensive care even after removal, with respiratory failure possible despite treatment. Thorough daily tick checks in tick-endemic areas are genuinely life-saving.
