Where else would you look if you wanted an ex adv eventer on loan, not for jumping but to learn the more advanced dressage movements on? I tried BE website.
I know of one in South Wales -
Advertising here might be good, plus putting up notices at your local tack shop,
feed store and farriers forge/ van.
Best of luck,

Does it have to be ex-eventer? There are normally a few advanced dressage horses for loan on places like Horsequest if you're not wanting the jumping side.
A wanted ad on all the usual sites, - can you do wanted ads on BE web site.
If you want to do dressage why an eventer rather than a dressage horse looking for a less competitive life? Eventing dressage types are quite different from dressage dressage!
