Today's WP horses are bred for the arena, not for working cattle or going out on trails (otherwise they'd be, well, working cow horses or trail horses).
They are also not made to be
"always wanting to go faster but they keep that in check just because you ask them to and you're a team and then regularily, when the ground is good and it's safe, you allow them to go as fast as they want
I guarantee if you get on a NATURALLY bred WP horse and ask them to go as fast as they want, you won't get much
The thrill and adrenline us WP riders get is going out in a huge class and making a cut or winning the class- there is no better feeling than seeing your TEAM WORK pay off.
We have bonds with our horses and if we don't get along, it's obvious.
Also, WP horses aren't dead, expressionless horses who have no personality.
They run, they buck, they snort, and have a good time out in the pasture although I must say my guys look like wusses trying to "run' with my gamer and trail horse...they couldn't keep up if they tried (because they are NATURALLY slow legged).
My gelding (who will be an all-around pleasure horse) follows me EVERYWHERE, he sees me and nickers, stands at the fence and watches me walk away...obviously he is a happy horse that shares a great bond with me.
