If I were riding in an arena with other people, no, just because of the sound/ringer, or the commotion it would cause if it fell out and everyone had to stop because I had to get off and grab it haha. But if I were by myself in any scenario, I would most likely have it
I think that depends upon your horse! One of the horses that ride! likes classical music!!!! And it calms him down if I'm trying to do something new that he would otherwise think was scary!!!! He can be a baby☺ Hhhaaahhaa but if your horse Spooks and doesn't like noise I wouldn't us your phone wall ridding!!!
