Hi, I am new to this site. I have a show coming up in a couple of weeks. I really want to ride a horse named Dee Dee in the show but the barn owner is nervous about her going. I hav been riding her 4 to 5 times a week with 2 to 3 lessons a week. THe last show Dee Dee was it she was really nervous and reared and flipped over on a girl in the ring. The owner is letting me take her but I don't want to get hurt she is very big about 17.3 hands and I don't want Dee Dee to get hurt, so is there anything I can do to calm her down?
