What should you know about tetanus shot for horses?

Tetanus bacteria can enter through a small puncture, nail injury, laceration, injection site, or surgical wound. Horses are particularly vulnerable when a wound is deep or difficult to clean. The toxin can cause tightening of the muscles, a stiff gait, a raised or rigid tail, difficulty chewing, sensitivity to sound or movement, and spasms. Vaccination prepares the horse's immune response, while prompt wound evaluation addresses the exposure itself.

Keep the horse's vaccination record available and ask an equine veterinarian when the next dose is due. After an injury, move the horse calmly to a safe area and contact the veterinarian, even if the opening looks small. Do not probe for a buried object or pour irritating substances into a wound. Follow instructions for cleaning, medication, and observation. Tell the veterinarian about the injury, the time it occurred, the horse's last vaccine, and any recent procedure.

Treat a puncture wound, nail injury, dirty cut, or unexplained stiffness as a reason for prompt veterinary advice. Emergency signs include a rigid posture, repeated muscle spasms, trouble swallowing, reduced ability to open the mouth, falling, or breathing difficulty. Limit bright light, loud sounds, and unnecessary movement while waiting, because stimulation may worsen spasms.

Ask which tetanus product and schedule fit the horse, whether the injury changes the plan, whether wound exploration is needed, and how to monitor eating, movement, and breathing at home. Confirm when the horse can return to normal activity.
