I have a 13 year old gelding that came into my family at the age of 9. He was extremely pushy and dangerously herd bound (rearing, striking, kicking, biting when you got him away from the herd).
I have trained him so that I can take him on a ride by himself and he is fine. Not even whinnying to the herd. He isn't dangerous anymore on that issue, thankfully.
My problem is that he avoids the bit all the time. I tried riding him in a halter and he is so pushy that I had no control what so ever. So I bumped it up to a bosal, he was a little better, I could control him somewhat, but still very pushy, and ended up with his jaw getting rubbed raw from the bosal. I figured that it was hurting more than helping so I put him back in a snaffle.
He responds to the snaffle the best of all, so I've kept him in it.
I have fairly soft hands and I don't yard on my horse's mouth, but as soon as you put the slightest pressure on the bit my horse opens his mouth. He did this from when I first got him.
I use a D-ring, sweet iron snaffle, with copper inlay. My instructor told me to get a nose band and put it on loosely so he can't jack open his mouth and avoid the bit.
I think this is more of a habit then any pain, because I am soft with my hands.
What are your ideas, and what do you think of putting a nose band on him.
The bit looks similar to this one
The set up on him, he has a halter on under bridle.
