I have worked closely with a chiropractor and she said said he was fine. She has done work on him however. As far as his hind end, its rather more of "one bad leg" issue that I constantly face. On his rear left we have had a strained gaskin, torn stifle, bone chip and a deep tissue injury on that hip. Can horses have cursed legs? Ha.
And yes he is more TB than QH. His sire is Flaming Jet, an own son of Jet deck which is a line riddled with a lot of TB. His TB side he is a great grandson of Seattle slew
