Yes sometimes she will drop the rails but most of the time she will trot over them and trip. When i try to canter her over she refuses.
Training a horse to jump isn’t an event it’s a process and every horse learns at a different pace. If your horse isn’t having any problems such as droppping rails all the time/stopping I don’t see why you can’t do some small verticals.
I agree with Ellie. Unless your horse isn’t getting over them then you can probably put them up.
Unless there’s any specific problems just put them up and see what happens, only way to tell!
What problem are you actually having with your horse? As in he’s still dropping rails?
