My 12 year old gelding does not like to ride out alone... yesterday he was so nervous he was spinning and throwing his head and would NOT go further than maybe 100 yards from the barn. ( I rarely ride alone.. so I can't say if this is new behavior or not..) Since I was alone, and not interested in getting thrown, he ended up winning that one.
So today I took him out on a lead line.. right past where he would NOT go yesterday. No problem at all.
It seems he is fine if he can see me - but once on his back, and out of his sight, he panics when he gets away from the barn.
So - I guess he is not really buddy sour.. not sure what to call it... but I am taking suggestions...
