This is what I did with my mare:
Taught her to turn on the haunches and forehand, and waited until she would move away by me simply walking into her shoulder or hip depending on what I wanted her to do.
Then I started to introduce the side pass by asking her to move her shoulder and butt over at the same time into a fence. At first she didn't understand and moved diagonally but now she does it fine.
Start from the ground and then start under saddle the same as on the ground.
Praise him for every little step he takes even if its only a little at first. Then when he gets better at it ask for more.
**If someone has already posted pretty much the same thing sorry, could only read the first post I'm kind of in a hurry. Sorry!**
It's something you need almost like air or water. ♥
