He was checked by a vet and a chiropractor 2 months ago and he's sound. It's really not as big of a deal as I think ya'll are making it out as, usually just one crow hop the first time I ask for canter, once he knows I'm consistent he doesn't do it the rest of the ride.
Both of our saddles fit him good, and we both use plenty of padding, a navajo rug and either an air ride or a weaver neoprene on top.
We are both riding with spurs now, and I don't think riding him in 2 different bits is a big deal, as he responds very well to both. My mare is ridden with anything from an english bridle with a high port to western french links and everything inbetween depending on who rides her and she never seems confused.
And he's not confused we ride him in a very similar manner, which is why I'm making sure the cues she uses won't confuse him with a curb bit, as that is what she wants to transfer him to. I ride alot of different horses for different people and I understand the importance of riding in a similar manner, which is why I am sure what cues they use with their horse. The the only thing I thought might be confusing him was the picking up on the rein with the curb bit as a cue.
The goal with this horse is for my girlfriend to learn how to ride in spurs, transition him from the snaffle to a curb, stop him from crow hopping in the first transition, and put a lot of trail miles on him. I am not trying to argue in any sort, and I appriciate the help ya'll are giving me, I know you are just concerned for the horses well being. Just want to make sure we are on the same page.
