Tick Paralysis in Dogs and Livestock

Tick paralysis is caused by a neurotoxin in tick saliva that produces rapidly progressive ascending paralysis in dogs, livestock, and occasionally humans.

Key Facts

Several tick species cause paralysis including Ixodes holocyclus in Australia
Signs include progressive weakness starting in the hindlimbs within days of tick attachment
The condition is potentially fatal if the tick is not found and removed
Australian paralysis tick cases are most common in spring and summer
Finding and removing the tick typically leads to rapid recovery

Welfare Considerations

Animals with tick paralysis experience frightening progressive loss of muscle function including inability to walk, swallow, and eventually breathe. Early detection and tick removal is life-saving. Tick antiserum is used in severe Australian cases. Prevention through tick control products eliminates this form of suffering.

What You Can Do

Check dogs and livestock thoroughly for ticks after time in tick habitat
Use effective tick prevention products in high-risk areas and seasons
Know how to properly remove a tick without squeezing the body
