She was doing it at the trot tonight off and on and not much at the walk. I have heard her do it on longer trail rides but once again thought maybe she was just out of shape. It doesn't seem to bother her at all, she still pretty spunky when being ridden. She also does not make this noise at all while lunging.
Could this really be roaring since its only after being ridden after long periods of time or when being "worked." She does not act really fatigued or out of breath, but she does have the typical build for this condition it sounds like.
Anybody have a horse that roars and still ride, work, and show it?
