Last evening I went for a light hack. He hadnt worked hard since SUnday, and spent all Monday and Tuesday outside in his paddock. I tacked him up and we went to the ring. It was colder than its been all year. From the ring you can see another farm with two new TBs in the pasture. They just came from the keenland sale, still have numbers on their hips! I got on my boy and began trotting a bit. Then I noticed the two TBs began charging around and making a lot of noise. Then I could hear hooves on the road and saw a guy in full Western garb come galloping by on his palomino. The two TBs were going NUTS and I did the fastest dismount ever. My boy was by then very worked up and focused on those other TBs.
I got the lunge line and got him ready to work that way. When he started out I have NEVER seen him buck like he did on the lunge line. He went into full out bronco mode and squealed like crazy. I kept transitioning between walk and canter and each time he started the canter his back feet went sky high. I couldnt believe it! He I kept bringing him back to trot and starting again and we didnt finish until he cantered calmly in both directions. The only reason we go there at all is because he was visibly tired. I walked him cool for quite a while and he was a nice calm boy then.
Seeing this type of bucking 3 days before our next show is not helpful. He has never done this with me on him (minor crow hops only when he resists something)
My questions are this:
1) Is it normal for a horse to all-out buck on the lunge and never do it with a ride?
2) Did seeing the other TBs get crazy cause him to "follow the herd" and spin him up?
3) What means he wont do this on Sunday?
Any advice is welcome. My trainer is getting on him today to evaluate how he is doing.
