This has been confusing both me and the barn owner. She has one horse, named Heart, that at first was really shy about everything. Head shy, spooked at everything including mud, and just was all around spooky. With work from everyone we got Heart alot better. I could run up to him, pet his head, and run away...without spooking...where as if I did that before, he'd have a heart attack.
He had a whole turn around...he was great...he still spooked occasionally, but he was still 200% better than he was when I first started riding at the barn.
Since he was getting really herd bound, the barn owner moved him to a different pasture with just one horse. Heart and the other horse got along fine...Heart was the dominant one, so he wasn't picked on at all.
Since he was picking on the other horse way too much, we moved him back last Sunday, but he was worse than when I first started. He wouldn't let us catch him in the field...he wouldn't let you touch him....he'd flintch at EVERYTHING (trees, people, other horses, leaves)...when I tried to put a saddle pad on him, he tried to run away, but realizing he was in a stall and couldn't he tried to pin me to a wall and kick me.
Then once we got the saddle and such on him, we would walk around and all of a sudden he's start shaking really bad all over...he'd try to bolt more than normal (he'd usually always try to bolt...but not as often as he did when I was riding him on Sunday).
Any idea on what would be causing such a turn around for him? We are totally stumped. We were thinking of maybe Spring Fever, but he was fine when the seasons were changing before.
