Here's a good riddle. Over the past 2 weeks, this has been getting more noticeable. Left lead canter is perfect, round engaged and he reaches into the bit. Trot both directions is metronome perfect. You could set a watch to it. As soon as we pick up the right lead canter, he starts flipping his entire head and neck not necessarily in sync with the rhythm. My very first instinct is teeth, but he just had them done a few weeks ago. I had them done when I did because I thought this was the result of some hooks on his teeth, but guess not. At the walk, if I leave the rein slack, he tosses his head to a lesser degree until I take up the slack. His bridle is new as of last November and his bit has not changed. I'm going to try adjusting the bit a little lower in his mouth tomorrow and longe him at the canter to see if he tossed his head without a bridle on. Maybe tooth abscess brewing?
I attempted to investigate the possibility of pain. His back does not appear to be sore. Today he did leg yield, shoulder-in and haunches-in at the walk in both directions. The only resistance was to shoulder-in tracking right. I'm thinking maybe sore neck since he did get a nasty bite there a few weeks ago, but would think that would be improving, not going down hill at this point. He is willingly jumping both directions, but the head tossing comes back into play any time we land on and continue on the right lead.
Lastly attitude. We have been jumping higher, and I have been asking much much more of him at the canter over the past few months. He has a club foot on his right front, and I know that lead is more difficult for him. Is it possible I just need to send him more forward? I've been reluctant to do just that in case it really is some result of pain. I don't want to aggravate the situation if it's not in his head.
Vet is coming this week for shots, so I guess I will be budgeting more $$ now for the visit. He's getting a massage soon in case it's just tight muscles. Any ideas of what's going on here?
