I have anew horse who is an OTTB that has teh basics of dressage. IN general he is reactive and will frame up fairly easily though OI am currently working on getting him to stretch out and down to help develop his topline; he is lacking muscle and a little weight right now.
He was trained in and is still being ridden in a french link loose ring snaffle which he chews on constantly. Others have said he doesn't open his mouth but you can hear him chewing on the bit.
He was vetted out on a pre-purchase exam and the vet indicated his teeth were fine so no concerns there. He isn't tossing his head or avoiding the bit in any way.
Any ideas on what is going on?
