what jayde said i don't particularly like ear plugs on them but it does block the sound but he might not like it
At a show where there is lots of activity ear plugs are really good
Take him away from the action if you can, or find a quiet calmer spot. I know some people like to add a calming supplement to horses' feed before a show, but that's up to you. Walk him in slow circles and talk calmly to him. Hope it helps :)
Ear poms are amazing, blocks out most of the noise
I would try to talk to him and just relax my body.
He's fine with all of that and he loves listening to music 😂 Just he gets stressed at competitions
F I have the same problem
So, just do a lot of ground work with him. Get him use to flashing lights. And play music near him so he gets use to speakers
