The results will be on iEquine likely tomorrow.
As far as why the “shoes” on western horses? Some horses do require inventive shoeing to keep sound. When used for movement in a western horse, you don’t want so much knee as a little more “roll” in the stride. You see it much more in the HA’s than the PB’s, where you have a lot of QH crosses who just don’t have the same level of roll.
With the Arabian western horses I’ve ridden, the best naturally have that roll, and the movement is enhanced through correct training, and getting the horse to work off their hind end in TRUE collection, rather than a faked version. Sadly, like in EVERY breed/discipline on the planet, some trainers sacrifice correctness for expediency. I usually do a lot of leg yielding, shoulder in, haunches in, spirals, etc to build the strength and carrying ability of the hindquarters on the horses I ride (and my trainer is all for it!).
I will say that a correctly trained Arabian western horse is incredibly comfortable, and a true joy to ride. One of my favorites LOOKS bouncier, but he’s incredibly smooth and comfortable, because he really works off the hind.
Oh, and for more knee on the hunters? That’s slowly falling out of favor. The winning hunters now are looking for more length of stride than knee, and it’s showing at Scottsdale this year. You still want some knee, but not the extremes we saw a few years ago.
