Well, but both are true of the western pleasure horse. If you look at the way they are built, that’s typically how a good one moves somewhat naturally. I’ve seen babies on the longe line jogging very slowly and loping with a level (and slow) topline.[/QUOTE]
I actually object to this argument though I’ve heard it MANY times, because it’s twisting the definition of natural. They’ve been SELECTIVELY bred to move like this, it’s not natural for a horse to do so. Even then, it’s not healthy or conducive to soundness to move like that, even for the ones who’s tendency is to move that way by default.
The back of that horse is not hollow if you envision his skeletal structure. His head has been raised in the style that saddlebreds are shown in which makes that deceiving, but unlike modern competition, the base of his neck is not dropped in the process. It’s why I used that photo rather than a more modern one…same reason I used Alerich rather than a more recent dressage photo.
WP is analogous to the exact opposite of what long and low is when ridden correctly. Long and low is not just riding with a low head and loose reins, though even many dressage riders don’t get that. Done properly, long and low asks the horse to reach into the bridle (extending the top line), reach down to do so (raising the back), but to tuck and engage the pelvis (not having it straggling behind with an improperly flexed SI).
WP as shown is just plodding along on the forehand, backed completely off the bit, with the head lowered. Because the horse isn’t reaching into the bridle lowering the head serves no purpose, since it’s not making use of stretching the nuchal ligament to help support the back. Likewise since there’s no engagement of the SI, there’s none of the physiotheraputic stretch of proper long and low.
I debate the “not widely used” part, in light of these and the many “how do I retrain this former WP horse” threads that are all over the place.
