i would never eecommend the sue of a daisy rein with a horse who has not been physically checked: to eliminate pain (the most common factor) her saddle, back, teeth, bit fit and physiology all need to be checked before anything.
what do you feed ehr? how much excerssie is she getting? when did this problem start? you need to find out why she buckes, rather than just treating the symptoms; she is trying to tell you something in the only way she can, and if you don't listen then she'll feel that she has to go to more extreme measures to get you to.
has anything changed in her routine/life when the bucking began? or has it always eben there?
i would enevr forcefully, physically restrict your horse from bucking: if she is unable to she may well use other bad behaviours to show her feelings instead. plus, most importantly, you will not be removing her feel for the need to buck, and theefore you want to stop her wanting to do it, ratehr than forcing ehr to which will not solve the issue.
you need to consider all of these options: does she do it during the transition from trot to canter, for example?
and also, a few bucks to let off steam afetr being stabled all day/night, or at the start is acceptable, especially during training: try lunging her for a few mins to allow her to let off steam forst, before riding.
eliminating the cause will eliminate the reaction, so find out what it/they are!
good luck
