Today, we’re diving into an important topic. How to Rescue an Overheating Horse: Warning Signs You’re Missing, how to help them cool down, and how to prevent heat stress in horses during hot weather.


Why Do Horses Overheat?

Horses can overheat for a variety of reasons, including:

  • Lack of fitness
  • High heat and humidity (⚠️ Heat + Humidity >150? Take caution)
  • Poor sweating ability (like anhidrosis)
  • Breed differences (heavier breeds struggle more)
  • Thick or long coats

The most common cause of overheating is working a horse in extreme heat and humidity without enough breaks, shade, or hydration.
