Hi, I have a question for anyone to answer.  I have a TB mare who has been bucking at the canter (she lunges fine at the canter and even lunges over jumps at the canter).  Her saddle fits and I’ve had 2 vets check her out.  One was specialized in chiro adjustments & acupuncture.  The only thing he found wrong with her was she was short strided after he flexed her right hind leg.  So he did an adjustment & acupuncture (on her hindquarters).  The next day she came up sore in her back (you can squeeze around her back bone behind the withers and she really flinches).  Is this normal after a chiro adjustment??  Has anyone experienced anything like this?  Thanks so much.
