I've noticed lately that my gelding trots in a hollow outline. I don't really know what to do about it...a martingale doesn't really seem to help. Here's what he does in his other gaits:
Walk- he walks nicely with a rounded outline, steady gait and nice movement
Trot- head very high and straight with a hollow outline. he arches his neck nicely with a round outline when I lunge him and when he trots in the pasture, but while being ridden, his trot is a bit jerky with a HOLLOW outline.
Canter- high head, also hollow outline. Very jerky canter.
Gallop- smooth, flowing canter, nice head movement, very comfortable.
So...what am I doing wrong??? Or what is my horse dung wrong? I have a feeling that it's me....I've tried letting the reins a bit longer but he still does it. I ride bareback by the way. Maybe he's uncomfortable...? I ride in a snaffle bit and also use a neck strap (a non-rubbing lead rope) to keep balance. Otherwise I'd go bouncing around on his back! Here's my list of what might have him trot and canter in a hollow outline:
-he was a pacer and I heard that some young ex-racers travel in a hollow outline
- he doesn't like my weight on him bareback. (but he gallops and walks just fine)
- the pressure on the neckstrap is causing him to lift his head.
My main guess is the neck strap pressure, because I only apply pressure on it wen I trot or canter, because it's hardest to stay on then. Walk and gallop is really smooth with Luca (my horse). I will buy a saddle soon, but I don't want to stop exercising him. Should I stop riding him until I get a saddle and the neckstrap won't be needed anymore? Or is there some way to improve his outline? Advice needed please!
