In some cases, the dog will not be able to move its legs at all, a condition of total paralysis, and in other cases, there may still be some communication between the brain and spine and the dog will only appear to be weak, or will have difficulty moving its legs, a condition called paresis â partial paralysis.here are also cases where a dog may be paralyzed in all four legs (tetraplegia), and in others, the dog may be able to control the movement in some of its legs but not all.
Generally, this condition is associated with ticks attached around the head area, particularly at the base of the skull. Ticks that have been implicated in tick paralysis in the United States are the Rocky Mountain wood tick, the lone star tick, and the American dog tick. However, not all members of a species cause tick paralysis. The toxin that causes this condition is part of the salivary fluid that the tick injects.
