I'm a short person, even in my work/riding boots, and I have a 6 year old dinosaur mare that I have started undersaddle. The trouble is that she's 18hh and still growing. She's also a very suspicous, spooky, snorty, and alert horse (we're doing a LOT of desensitizing) so she does not naturally stand with her head anywhere near the ground. This can be bothersome when I am haltering and bridling her. Although she is a dear and doesn't mind me fumbling around on my tip toes, I'd like to teach her this so her future owners won't have the same trouble as me if they happen to be shorter than six feet.
I've never taught a horse to lower their head on command, so I would love some help! How did you teach this to other horses?
