Most gaited horses I know (actually all gaited horses that I know) gait best with their heads slightly up a bit, rather than down like a quarter horse. I have seen TWs that keep their heads very high with the "bob"; it seems to help with rhythm and momentum.
My horse (a KMH) doesn't "bob", but he does keep his head up. Now, one of the trainers at my barn has suggested that I TROT him, and work with his head down to round his back. This would only be done in the arena as an exercise; she is afraid his back is beginning to get too "hollow".
I had 1 gaited trainer tell me to "stretch the bit, and keep his head down" during the gait, but this was really tough for him to do! He lost so much rhythm and balance! But, I would love to be able to do this, because I don't want him to go back to the trot. I "paid extra" for his wonderful gait!!!
Has anyone else been concerned about a hollow back forming on their gaited horse? Can you gait with the head down? Or, do you trot your gaited horse often? I certainly want my horse's back to stay strong and pain free for as many years as possible, so I would love your feedback.
