Thank you everybody for the input.
It is just hard to imagine that a loss of trust has happened. He is so in-tune to me constantly, from the minute I walk into the barn he wants to be by my side. He watched my every single move. He is such an emotional horse and really looks for my company.
I rode him today, and he was back to his phenomenal self. The difference? I lunged him first, before even tacking him up, to let him get his 'crazies' out. He ran & bucked on the lunge, then once he settled, I took him back in & tacked up.
We put draw reins on him, but only had them tight enough to where if he tried to lift his head high enough to grab the bit & bolt, it would give some pressure and keep him from getting his head that high.
And he was amazing, exceptional even.
I changed the snaffle to a Boucher (sp?) to see if that helped, as it is a little thinner in the mouth piece, where was my snaffle is quite thick & very soft.
He was completely responsive, and was stretching through his back and down to the bit so nicely. He really was looking for the contact today, maybe only once or twice did the draw rein actually come into play. The rest of the entire ride by myself and my friend it wasn't used, was just there for us as something to hold.
It was so nice to have to push him forward again... =P
I think that the 'bolting' issue may just be excess energy that he doesn't know what to do with. Once he is concentrated and focused, like today, he works like an angel.
Thank you all for your input. :)
