I agree with all the suggestions so far and wanted to add one more unmentioned technique. While the you tube vidoe offered information about endorphins with a lowered head, there's another endorphin related technique that quickly results in a lowered head. I understand it's a bit controversial, but ENDOTAPPING has been a wonderful introduction to training my mare. If your not familiar with endosticks, or endotapping: It's just a firm foam ball on the end of a whip/crop/bat as opposed to a lash or loop. My mare had some challenges with nervousness, fleeing, and stiffness. I made an endotapper with a dressage whip, a foam ball (Walmart party supply sale), balloon, and liquid rubber or liquid electrical tape. Within the first 10 min. Every time I tapped her - and anywhere I tapped her- she immediately lowered her head and stood still. Some think it's just another desensitizing tool, but it's really helped my groundwork with my mare. I find just a couple minutes before we begin anything, and she's more receptive to working and feeling good.
Thank you for the explanation, IslandWave. (I often misunderstand posts!) I can understand the moving of the bit, now, too, as a way of saying: "You don't pull!--- but you do activate the bit, somehow."
IslandWave, if your interested in seeing the stages of endo tapping, search you tube "what is end tapping?" Equis University has a video featuring JP Giocomino and displaying the technique. From what I understand, he was involved in the research and development. My nervous mare found great relaxation through tapping, and we're working on adding movement to the training. However the lowering of her head happened within the first moments of it's introduction.best wishes. Posted via Mobile Device
