Tick Paralysis

Tick Paralysis

Not actually a disease as such but specifically in the Eastern border of Australia, there lives a tick called Ixodes holocyclus which results in a paralysis which will eventually kill the dog if not treated quickly enough with tick anti-serum. Usually you would notice that your dog's bark seems altered, it would act dull and depressed and then would be followed by a staggering gait. The paralysis spreads upwards to the neck and other muscles and the dog eventually dies from paralysis of the lung muscles.
