As some of you know, I have a 9 year old Haflinger cross gelding named Odin. He's a sweet little boy who loves to be with me, but lately he's been extremely frustrating. He's amazing on the ground; stands for hours in the cross-ties while being groomed, stands still while being tacked, leads wonderfully etc., but under saddle he's a different pony. He has his good days and his bad (lately, his days have been bad.) We've had days that we can get through a 2'3 course without hesitation, then others where he won't even jump 18 inch. I work him on the flat for about 25-30 minutes before I ask him to jump so he's plenty warmed up and ready to go.
In his bad days, he either tries to run off with me or refuses to move at all. All this bad behavior came about after he dumped me about a month ago. He has a clubbed hoof, but he's completely sound, so I don't know what's wrong with him. I recently switched him back to a loose snaffle from a jointed curb. He seems to be better now that he's the bit he was in to begin with, but he still has his iffy days.
One more thing for now.. He doesn't get the concept of lunging to save his life. I've tried numerous times to lung him and all he does is look at me like a have a million heads and trots back to me in that goofy, 'I can't be away from mommy for more than 5 minutes' way. He doesn't invade my space, he just has to be close to me. The only time he's successfully been lunged is when I was on him and my friend was on the ground.
Sorry about the rambling. Any advice?
