How do you spell woo like cowboys say to their horse?

Cowboys don't actually say "woo" to their horses. They typically use a variety of sounds and vocalizations, including:

* "Whoa" - This is the most common command for stopping a horse.

* "Giddy up" - Used to encourage the horse to move forward.

* "Haw" - To turn the horse to the left.

* "Gee" - To turn the horse to the right.

* "Click" - A gentle sound made with the tongue to encourage the horse to move forward or to indicate a change of direction.

So, while "woo" might be used in some cowboy movies, it's not a real cowboy command.
