Hey, I just recently purchased a wonder bit for my horse because some people had recommened it...well, my usual sweet horse was just mad it seemed! He was throwing his head, running off with me, and everytime any pressure was applied, like to stop, he would try and bite me. Has anyone else had this problem with this bit.. also I was using a jr cow horse bit before.. should there be that much difference in the bits to cause this or do yall think I've got something else to worry about?
