Thank you so much, yes it does—I was turning too quickly as there was mud in the arena and I’m afraid of the horse slipping.
Are you sure you don't turn too quickly after the jump? If it's a sharp turn it is more difficult to keep your canter, but with some work for you and your horse it will be easier!
Make sure you use your legs after the jump, while you are turning, especially your inside leg, so that your horse will turn correctly.
You can start by doing it after a ground poles, so that you don't focus on the jump but on your turn after the jump.
You can put several ground poles, or small fences, and you have to canter over every pole without trotting in the corners.
When it becomes easier for you, try with shorter turns, it will help you for jump off 😉
Hope It helps!
