The clinical appearance of this disease typically falls into two types: “aggressive” and “dumb.” Aggressive symptoms include combativeness and violent behavior, as well as sensitivity to touch and other kinds of stimulation. The “dumb” form of the disease causes the animal to be lethargic, weak in one or more limbs, and the inability to raise its head or make sounds because its throat and neck muscles are paralyzed. These symptoms are also synonymous with other types of disease so your veterinarian should be called right away to complete an evaluation and rule out other possibilities.
