i think that a stud chain really isnt that horrible. but you must make sure that you arent the one pulling on it. when ur horse pulls her head up, and she gets just a little pressure on the nose. just make sure you arent the one pulling! :)
Horse stud chains should be put on OVER the nose unless showing in western halter classes. For general handling and stud chain effectiveness, a stud chain should cross over the nose, through the ring on the halter on the opposite side, then be crossed under the jaw and clipped to the O ring on the near side of the halter, just below the buckle. This method of attachment maximizes control, ensures the halter isn't pulled askew by the chain, and minimizes the possibility of unintentional misuse. Never attach a stud chain under the jaw of a misbehaving horse. A stud chain attached in this way may encourage a horse to toss their head or rear.
best of luck! :)
