Drop Noseband - The nosepiece of this type of noseband should sit on the bony part of the nose, about four finger's width above the nostrils. The rings on which the chin strap portions of the noseband are attached should not come in contact with the bit. The chin strap should stretch down in front of the bit and be buckled under the jaw only snug enough that you can slip two fingers between it and the jaw bones. Take special care to be sure this type of noseband won't affect the horse's breathing after it is buckled into place.

Note: Nosebands function differently and produce varied results on horses. Always consult a trainer or a knowledgeable friend for help adjusting the noseband if you have questions about the way a particular style of noseband could influence your particular horse.

4) Adjust the Throatlatch.

Buckle the throatlatch so that you can fit four fingers between it and the underside of jaw-but not more. The throatlatch is intended to keep the bridle in place if the need arises during a ride. If it is adjusted too loosely, the throatlatch cannot perform its function if needed. If it is buckled too tightly, it can hamper the horse's breathing. Some dressage riders prefer to have a slightly shorter throatlatch adjustment than the four-finger rule provides.

5) Adjust the Curb Chain

If you're using a bit with a curb chain, such as a Kimberwick or Pelham, you will need to adjust the curb chain.

Untwist any kinks in the chain so that it will lie flat against the horse's chin when the bit moves. As a general guideline, hook the chain at a length that allows you put two fingers between the chain and your horse's chin. This guideline will have to be adjusted according to your horse's needs. Some horses require a very loose curb chain setting, while others need a more snug adjustment.
