This is what I would do, it should heal quicker if left alone as much as possible. I can’t see that you have anything to gain by struggling to keep bandaging the leg.
I’m in the you should sell camp, I get that you’ve invested a lot in this horse but he doesn’t sound like the right fit for you and I think both you and the horse would be happier with new partners.
I think it’s great, racing needs all the good publicity it can get and who would have thought that would come from an ex hurdler running on the all weather on a weekday evening 😀
No there won’t be as now we know he’s stopped hurdling and he has the speed to be a flat racer. It’s a surprisingly low key race as well so maybe they are just wanting a reasonable handicap mark
