Haley on Charlie, a Tennessee Walking horse. As Charlie walks, Haley gets shifted side to side. They say it is characteristic of a Tennessee Walking horse. The lateral movement is good for Haley because it will help strengthen her core muscle. Dravet syndrome has caused her to be low tone. If she sits too long, she slouches. Therefore it is good to be challenged through riding Charlie and other exercises they do on the horse. Thankfully (as you will see in this video) her side walkers will adjust her if she gets shifted too far over.
