Sure she's fluffy
, yup she has a short neck. But she is a nice looking mare who can move. Dressage is certainly a good career for her. Will she go GP? Probably not, but 98%+ of purpose-bred dressage horses don't, so I wouldn't let that stop you
FWIW, I have a friend with a horse competing at PSG/I-1, and he'll debut at I-2 this summer - that's piaffe, passage, 1-tempis, pirouettes, etc. He is 14.3H at withers, 15.2 at top of croup. Really. As my Brooklyn-born Granny used to say, "Ya neva know".
