thank you all for your suggestions!
Diva (the horse we are talking about) is a 3 day event horse, meaning we do 3 stages (dressage, cross country, show jumping). Show jumping is the only phase that allows bitless in Canada, and sadly takes place outdoors.
I was able to jump her bitless in her unfit/coming off lameness state, but as soon as I started doing set work she became way too hot and ignorant for the hackamore (stubben steeltek hackamore)
Yes, I'm aware of rules that insist on bits for comps(one rule I think is unfair), which is *one* reason I'd avoid comps for now. But I wonder, if there's nerve damage, can you be absolved of that rule if you have a vet report advising no bit?? Regardless, you've got to get her going well generally, before you can even see if she will go well in a bit, if she's obviously worried about the pain it's causing.
As for that 'hackamore', I'd start her in a *real* hack, a rope bridle or other bitless, but I would not recommend a mechanical leverage device like that stubben one generally. And yes, it sounds like this horse is rather 'ignorant' - or at the end of her tether from ignorant riders(not assuming nec. all you). The horse obviously need far better training, not just to be put in a bitless & Bob's your Uncle. It will take proper training & preparation to get up to the stage of jumping without getting 'hot' & out of control, regardless what equipment.
raised to tongue pressure is only applied when she leans)
Horses only 'lean' when a rider gives them something to lean on.
and go cross country in a medium shank pelham
I thought you said she couldn't be ridden outside?
Diva sees the chiropractor around monthly,
What body issues does she have, to necessitate that? That's another reason why I wouldn't be showjumping her, or other 'high impact' stuff, for now at least.
I recently tried the loose rein circle method but we ended up spinning on a ~8m circle for 5 minutes, no relaxation or slowing.
Maybe have the totally wrong idea, but sounds like you only tried this once? And you didn't actually ask the horse to slow, let it trot? And you gave up after only 5 minutes?
high quality hay, 1 scoop of high protein/fat/fibre (life line carb care) ark synergy, ark strategy, flax, hemp oil, electrolytes, and G’s formula.
Haven't looked up all those things to see what they all are, but why does she need all those things?
ridden 7 days a week: 1 jump lesson, 1 set work, 1 dressage lesson and 2-3 dressage schools (one normally is a walk/trot hack)
Sounds full on. Sounds like you are putting the 'cart before the horse' big time, with your ambitions for her. And the very last word above - I thought 'hack' was the English term for trail riding - again, thought you said she was no good outside?
