Ok so I have a 6 year old Amish broke American quarter horse who absolutely refused to take the bit. She see's the bridle and completely flips out, throwing her head and yanking against the rope, all the while sticking her head straight up in the air with her mouth clamped shut. Today I was thinking if a hackamore would be better because she is sensitive to neck reining and does just fine with a halter with a lead ripe as reins. Any suggestions??? :)
