What type of horse is the leader a wild herd?

There isn't a specific breed that's always the leader of a wild herd. The leader, typically a mare, is chosen by the herd based on several factors:

* Experience: Older mares tend to have more experience and knowledge of the area, making them valuable leaders.

* Strength and Courage: The leader needs to be strong enough to protect the herd and defend it from threats.

* Intelligence and Social Skills: Effective leaders need to be smart enough to make good decisions and navigate social dynamics within the herd.

Essentially, the leader is chosen based on its ability to lead and its overall fitness for the role. This can change over time as horses age or the herd dynamics shift.

While there's no specific breed that guarantees leadership, some horses are known to be more assertive and dominant than others. However, breed alone isn't a deciding factor.
