If you think it's 'you', can you have a trusted friend give her a try?
Also - could be your saddle in her way when she tries to stretch to pick up that lead.
For the saddle...I don't think that this is an issue either as I ride in my crates one day, bareback the next, my old barrel saddle and english once in awhile just to keep things interesting. She has had a problem with right with all of them......
You know.....she was used for a rope horse before I got her and maybe the folks who trained her would not let her go right. I have herd of that before, although it's a stupid idea if you ask me......
Well, maybe I need to totally rule out pain. Although I don't "think" it's a pain issue, I would rather be safe than sorry. Guess I will get her back to my chiro....then I can ask about massage. I seriously doubt there is one in my area other than if Syd my chiro does it. He usually tells me not to bring the horses back unless there is a problem, but this may be one of those problems........Thanks for all of the suggestions : )
