Introducing the Bit

Bit Selection for the First-Time Horse

Start with the mildest appropriate bit for your discipline: a smooth snaffle for western work, a gentle full-cheek or D-ring snaffle for English. The mouthpiece should be smooth, the size should fit the horse's mouth (1/4 inch of clearance on each side), and the bit should hang at the correct height — just enough to create 1-2 small wrinkles at the corner of the mouth, not pulling the corners up aggressively.

Do not start in a harsh bit. A young horse is learning what a bit is — starting with intensity is like teaching a child to write with a sharp pencil by poking them with it.

Headstall Introduction Before the Bit

Before the bit ever touches the horse's mouth, the horse should accept having the headstall put on and taken off without resistance. Practice bridling without a bit attached: slide the headstall over the ears, let the horse wear it, remove it. Do this until the horse drops its head and makes no effort to pull away.

The First Bit Experience

1. Warm the bit. A cold metal bit is unpleasant. Hold it in your hand until it's body temperature, or keep it indoors.
2. Let the horse mouth the bit in your hand. Hold it near the horse's lips and let it investigate and mouth it before it goes in.
3. Slide it in gently. Press your thumb against the corner of the horse's mouth to encourage it to open. Slide the bit in without clinking the teeth. Guide the headstall over the ears slowly.
4. Let the horse stand with the bit in for 5-10 minutes. Reward calm acceptance. Don't immediately put reins on and ask for anything.
5. Remove before the horse is tired of wearing it. End the session while the horse is still calm and accepting.

Building Positive Association

Some trainers dip the bit in molasses or apple juice for the first several sessions. The horse begins to salivate when the bit appears — salivation promotes a soft, accepting jaw. A horse chewing softly on a bit is relaxed. A horse with a clamped jaw or overbite is tense. Work to build the relaxed response from the start.
