Here's why:
* Fight or Flight Response: Horses are prey animals, meaning they are naturally equipped to escape predators. Their primary instinct is to flee from danger.
* Playing Dead: This is a strategy used by some animals to avoid being attacked, but it's not a common response in horses.
* Fight or Bite: While a horse might fight or bite if cornered or threatened, this is a secondary response. Their first instinct is to get away from the perceived threat.
Important Note: Even though a horse's primary instinct is to flee, fear can cause unpredictable behavior. Horses may react differently depending on their individual temperament, past experiences, and the perceived threat.
