Protect Your Horses

Disease activity shifts week to week. A few habits go a long way:

  • Check destination states for disease activity before you travel or compete
  • Isolate returning horses for 14–21 days when possible
  • Monitor temperatures daily — fever is often the first sign of EHV-1
  • Avoid nose-to-nose contact and don't share water buckets or equipment at events
  • Inspect wounds daily and keep them clean and covered
