I've been having an odd problem with my mare. Whenever I canter her down a road, or a trail, she goes sideways. I've had my friends observe this, and it is always the same. While at a canter, her hind quarters go to the left and her front end goes to the right, and she moves in a forward motion. It's the strangest thing! She is fine when cantering around an arena, but she cannot canter in a straight line without going sideways. And she isn't crossing her legs over like in a diagonal. I don't know how else to explain it. If anyone has any suggestions or ideas of why she is doing this and how to fix it I would really appreciate it. Thanks!
