* Communication: Tails are used for communication, just like a dog's wagging tail. They can express emotions like fear, excitement, or aggression through tail movements.
* Fly swatter: Tails act as a fly swatter, helping to keep pesky insects away from the pony's sensitive skin.
* Balance: While not as pronounced as in other animals, the tail can help with balance, especially when turning or running.
* Warmth: The tail can provide warmth during cold weather, especially for foals.
* Protection: In some cases, the tail can be used to defend against predators by swishing it around and potentially kicking with their hind legs.
So, ponies have tails for both practical and social reasons!
