If they are already used to a halter, then they are already used to a bridle w/ no bit. (a bridle is essentially a halter modified to hold a bit)
If you mean to introduce a bit into the equation, age wise I've seen it been introduced around a year old. BUT, FIRST the horse was taught properly about responding to pressure (lowering head, opening mouth, etc.) and was at a point in training where the groundwork had already been laid (if that makes sense,lol).
Basically, if the horse isn't ready to accept and respond correctly and calmly to pressure, you've got other things to work on first.
I just want to train my long yearling to accept the bit-no riding yet.
