Hoofpic, as ever, stop over thinking it...you want to go see her, go, you don't want to go, don't, it IS that simple.
She doesn't need time to think about it, she is a horse, rider gets off, puts her in the paddock, she goes back to thinking about food water and horse things. She is not a person, she does not think like a person, she does not do home work while you are not there.
Haven't read everything but really feet should not be an issue with a broke horse, who has her feet done, just pick them up and clean them job done...should be that easy, if it isn't then please get someone there to give you a hand and show you the best way.
I'm really glad that by BO found the best massage/ chiro person that she could and encourages all her competitive riders to have their horses checked out 3 times a year, and the rest once or twice if possible....
