I've just heard that the Canadian Dressage Organization has proposed a rule for 2013 to allow ear plugs in the show ring!!
If you are a member of this organization please send an email to firstname.lastname@example.org to say you do NOT support this rule change!!
Apparently the only people objecting to it are non-riders and it is likely to get passed! What a shame that the sport aiming to show the highest partnership between horse and riders is allowing ear plugs in the show ring.
