The mouthpiece of the Waterford Snaffle allows for even pressure over the horses tongue. This encourages the horse to salivate and gently mouth the bit, accepting and softening to the contact. The horse will relax the jaw and allow for more responsiveness to the riders rein aids. The Waterford discourages horses to lean on the rein as it becomes uncomfortable when he pulls. The Waterford is thus a moderate bit but can become harsh in stronger hands. A Waterford Snaffle needs to be 1/4 to 1/2 an inch larger than a horse’s normal bit size to fit correctly as the mouthpiece of the bit needs to curl slightly around the horse’s lips to allow it to work to its full potential. The brass material stimulates salivation which in turn encourages a softer mouth.
