Step 1
Ensure the curb bit is the right size and adjusted properly. It should be about a half-inch wider than the mouth and sit right on the corners of the mouth just making him "grin," or wrinkling the corners of his mouth a tiny bit.
-
Step 2
Use the proper metal. Start with a medium width curb bit made of stainless steel, sweet iron or copper with a low, wide port and short shanks. The curb bit works on a leverage principle. The longer the shanks and the more pull on the reins, the more pressure is applied to the horse's mouth and the top of the head.
-
Step 3
Adjust the curb strap properly. You should be able to rotate the shanks back 45 degrees before the strap or chain contacts the jaw. Ensure the chain lies flat and there are no barbs or rough edges.
-
Step 4
Introduce your horse to the use of the curb bit gradually. Put it on the horse and let him wear it around for a while without reins to become used to carrying the bit. Stay close and monitor your horse's actions, so he doesn't try to rub the bridle off or get his foot tangled in it.
-
Step 5
Ground drive your horse with the curb bit before riding with it. This will allow you to safely assess how the horse responds and allow him to get more accustomed to it.
-
Step 6
Ride with a light touch. Practice touch and release. Don't keep a steady pressure on the reins, or your horse is likely to rebel. At the very least, he will become hard-mouthed, and you'll have to graduate to more and more severe bits.
