I need to use the arena because that is the best footing and where the jumps are. Of course I want to get her over this irrational fear. I don't remember anything bad happening to her there. Its very strange. Otherwise she is not a spooky horse for the most part. I don't think its just an act, why would she run from her hay then?
I plan on spending a lot of time in there until she gets over it but was wondering if anyone had any suggestions.
