Vega is the spirited type. She's always on the move, unless its time to eat. There was one time during the summer when I went to see her that she was just like standing in the stall, head lowered and just seemed very out of it. My boyfriend and I thought it was heat stroke, or the beginning of it since she is out from 8am-4pm in direct sunlight. I hosed her off and she seemed fine. I don't know if that was an episode, but there hasnt been anything since. There is one thing tho, I started teaching her to jump, with ground poles and small cross rails, and one time we were jumping, she did it fine, but as a I rounded a turn, she had a funky step. It's like her leg buckled but she caught herself. I immediately got off and walked her so it could see her legs move. She's done that a few times when I graze her, but I didn't think it was anything. When I see her today, I'm going to take a video and post it, so you can get a better idea on how she moves.
I was up til about 3:30 yesterday reading all about HyPP, trying to get as much information as possible and just learn about it. Someone at my barn mentioned to me that her horse and my horse are related because they both have Impressive in their show name and I thought it was pretty cool, but not anymore. I have to ask if she got her horse tested, because some of the things i've read where it was just out of the blue really really scared me
