Has anybody seen anything similar to this lameness before? Worst of it starts at about 40s into video.
-manifested the very first time when pony was in dressage training and was ridden very agressively deep.
-only occurs UNDER SADDLE, not on the lunge line, even when side reins are used.
-it is intermittant and shows up only during ring work, and lots of circles and bending. At the trot there is no head bob, he just gets really giraffe-like, hollow, and resistant.
- the more contact used the worse it gets, but it also happens without a bit, and when riding bareback.
-never happens during trail rides, and if little ring work is done can go months without occurring.
-vet thinks there is some hock arthritis even though x-rays are clear but couldn't really explain what was happening (to be fair he hardly did it when she was there)
-has had chiro, acupuncture with no improvement.
