What a great example of how we use our bodies to better communicate with our horses! Your pony follows you around when your back is turned to him, which is exactly what he would do with others in a herd. When you face him, he moves awaywhich, in equine etiquette, is perfect manners!
Let’s teach him to better understand those silly two-legged horses he lives with now! Begin by keeping some yummy treats in your pocket. Instead of facing him, turn to the side, or even turn your back to him. Give a verbal cue to come toward you (“move up,” “here,” or even just his name) and wait. When he approaches, give him a treat, walk away and repeat. If he just follows along, watch what happens when you face him and back up instead; he probably will stop and wait for you to turn. After a few sessions, he likely will approach on the verbal cue.
