  1. Yes, only deep wounds risk tetanus
  2. Yes, only wounds near the hooves count
  3. No, wound severity does not predict tetanus risk ✔

Why: The AAEP says all horses are at risk of tetanus, and the severity of a wound does not predict the risk. Puncture wounds, cuts and surgical incisions can all lead to infection, which is why yearly vaccination matters.

Huh, didn't know that: The AAEP recommends annual tetanus vaccination for previously vaccinated adult horses.
