My 5 y.o Paint mare, Cheyanne is super lazy.....last year she had a filly around this time, and her previous owner I just got her a month ago last monday, let her go and she is probaley unfit. When I put my inside leg back to push her into a canter ( I ride English) she comes to a dead stop. She was broke western but is taking english really well. I have jumped her 4th hole and she has never jumped that high before, her old owner only took her over logs out on trails. She seems to liek the outdoor arena better than the inside arena, she has more get up and go out there...and to make it worse she does infacted have high withers. To get her moving and to get her to keep moving, I use a crop I just tape her shoulder twice and she listens, but I don't want to have to keep using this method. What should I do!?
