I can't thank everyone enough(: he's the best horse I've ever came across... He has changed so much since I rescued him. When he eats I can lay spread out on his back, my head resting on his butt and he wont move hardly(: Such a great napping place and such a great friend!
Gosh, your guy reminds me of an Arab I kinda rescued, who also turned gorgeous with proper care! Great Job!:)
I want to suggest that you make sure that his saddle is not sitting on his scapular bones (akin to our wing bones). It looks to me like the saddle is atop his scapulae.(sp?)
The horse will hunch his shoulders to escape the pinch, won't be able to go forward freely in any gait. Perhaps you've seen horses with that hunched look, that's become permanent over years of saddle-on-scapulae.
If you find the back edge of the bone, saddle needs to be behind it, yet not only that, but even further than at horse's standstill, because scapula moves back even farther when moving forward.
Note: if he's already hunched at all, be prepared to keep adjusting saddle back, till he's "unhunched".
