what are the inherent 
  dangers in dressage?  I only play around with it and other than my horse 
  spooking at those dang letters on the side of the arena, nothing dangerous has 
  occurred yet.  'Course I am to dressage as you are to endurance -- never 
  done it competitively.
   
  The dangers are less 
  obvious than those inherent to endurance and eventing.  Basically, what 
  sometimes happens, particularly with talented and (usually) large horses is 
  that people push them too fast and ask for collection too quickly.  This 
  places strain on young joints, particularly, I'm told, the hocks.  
  
   
  A vet once told me that he injects 
  more dressage horses' hocks than any other equine athlete.  That's quite 
  scary.
   
  If you take your time, and do it 
  properly, there should be no dangers (unlike the other equestrian sports, 
  which are probably "dangerous" in and of themselves, and all you can do is 
  minimise the danger).
   
  Unless, of course, you were doing 
  dressage with Toc in his younger days : then it was an inherently dangerous 
  sport for the rider <g>
