Keep your leg on to the approach. And maybe give a tap of the whip on the shoulder. Just to keep him alert and knowing that your confident to go over it. Remain positive because he will reflect on that. Don’t get mad if he stops and walks over it. But maybe canter I’ve the jump and make the line to approach the jump tight so he has less time to think about stopping xx
Let them look at the fence before if there refusing but doesn't seem like the horses problem x keep pressure on and ride deep into your fence x
Agree, this is a rider issue not a horse issue. He’s doing exactly what you’re asking, so make sure you’re asking him to jump by keeping your leg on and a consistent pace to the jump.
Ride deep all the way to the jump. I used to ride western so the way that helped me was to think of how you sit when you gallop. You sit back and deep into the saddle, and keep your leg on all the way to the jump.
Trust in your horse make sure your not holding him back
Check tack etc and make sure you are not checking him as you approach fence. Go back to poles get confident build up to grid work at correct distances.
