I have a great 9 year-old Draft-X mare. I've owned her for several years and she is a great mount and friend. One draw back is that when we go on a 2+ hours trail ride, which is frequently, she gets a little jiggy on the way back. I've done alot of the recommended training routines with a little success but not completely. She does not relax comming back. I have narrowed it down to one strong possibility. Annie does not urinate while under saddle. She only will urinate in her stall or in the turn out area. I have seen her hold it for 5+ hours. Once I put her back in the stall after a ride, she immediately urinates. I feel bad for her because I'm sure she is uncomfortable. It also makes for a difficult return trip for both of us. Unfortunately, I don't have that kind of time (5+ hours) to stay out with her on a regular basis to train her that it's ok to go while we're out riding. Anybody have a suggestion as to how to correct this? Thanks.
