Seems like I usually see these on the left side, but I wasn’t sure if there was a general rule for this or not. I thought I remembered reading about someone who put hers on the right side so if horse knocked handler, handler was less likely to get a body part scratched by the plate.
Search turned up where to put a martingale plate and where to get nameplates but nothing on which side for halter plates.
What do you do?
