Horse Tetanus Symptoms

Tetanus is a serious disease caused by the bacterium Clostridium tetani. These bacteria are common in soil and in animal feces. They can cause life-threatening central nervous symptoms when they enter the body, typically through a puncture wound. A horse's environment may make it more susceptible to this disease, and prognosis is not good if the horse has not been vaccinated.

  1. Infection

    • A puncture wound on the foot is a frequent way a horse contracts tetanus. Any horse with this type of injury should be seen promptly for veterinary treatment.

    Third Eyelid

    • An early symptom of tetanus in a horse is protrusion of the third eyelid, a transparent or white membrane under the upper eyelid. This membrane begins protruding across the eye, especially if the horse is startled.

    Primary Symptom

    • The primary sign of tetanus is spastic paralysis, or painful muscle tightening. The horse will develop a stiff gait and show difficulty in moving. Back and neck spasms make him hold his head outward.

    Lockjaw

    • Tetanus is commonly called "lockjaw" because it results in the affected person or animal being unable to open the mouth or swallow. An infected horse will have difficulty eating, and the mouth may become drawn back, showing the teeth.

    Stimulation Sensitivity

    • Horses with tetanus become highly sensitive to light, sound and touch. They jump and make anxious noises, and may show aggressive behavior.

    Treatment

    • Treatment for horses with tetanus includes antibiotics, antitoxins and sedatives. Treatment is intensive, and the horse will need much attention, usually for several weeks, including protection from light and sound.
