Don’t be disappointed. Your score means you did nothing to interrupt him which is a great starting point. You realise how lucky you are. Most people do not get a school master to teach them.
Just a little word of warning, now that your eyes have been opened a little bit.
To bring HJ’s nose closer to his chest, you do not do this by pulling on the reins. You have to push him from behind into a holding rein, that the inside rein gives, as a reward, and resets to the same place with the reins.
That is why you got the comments to put the leg on. The nose will not come closer to the chest without leg.
You are looking for the face to be vertical to the ground. The muzzle should not be closer to the chest than the poll.
You want the poll to be the highest point of his head. The third vertebrae back should not be higher than the poll.
You want to lengthen the top of his neck from in front of the saddle up to the poll. You don’t want any muscle under the neck.
It will not happen overnight.
I saw a post on Facebook yesterday.
It takes 10 years to learn how to sit on a horse.
It takes another 10 years to learn how to influence a horse.
It takes another 10 years to learn how to meaningful influence a horse.
Oh and the purchase price is always the cheapest part of a horse!
Hugh will teach you are lot, however lessons will be invaluable, even if they are from DD.
