I have to agree with the posters who have pointed out that bigger horses are delicate and can have difficulty balancing themselves.
Just at face value it sounds to me like this horse is saying he needs more time to develop and learn to balance his massive body (if he is 18hh then I’m assuming he has a massive body). 6 is awfully young for most warmbloods, he still has a lot of maturing to do both physically and mentally.
As frustrating as it can be for the rider to keep the horse doing simple things (maybe in this case mostly walk trot), it might be that he is not ready for the canter work. You don’t want to sour him if he is uncomfortable because it might really develop into a dirty habit and not just the protests of an awkward youngster. Better to have him willing and happy in the canter later on when he’s stronger and more together, then getting into a pissing match now that can only get one of you hurt.
When I’ve worked with 17+ horses and some smaller too, I’ve usually spent the first year or two of training including only the brief canter transition in our workouts. When I do start the more serious work I’ll try to begin on a 30 meter circle or larger or even let the horse develop some canter on long straight lines out on a hack. Seems that some get a bit panicked when they feel the confinement of the smaller space requiring more collection and balance.
Just my two cents, best of luck to you and the horse. Keep yourself safe, that’s a long way down!![/QUOTE]
I agree very much!!
