Question time again, this one is from Sheila in British Columbia, Canada, who writes: My 5yr Dutch WB gelding has "shivers". I bought him end of Aug. 2007, the owner did not disclose this condition and I bought him on her good word. His dressage training is coming along well, but slowly, but his symptoms (muscle weakness esp.) markedly increased when I put him at an indoor barn for one month. Since he's been home, living in a large field, he has now returned to full strength. I believe this to be a great lesson for me, but how can he be helped, what does he need?
