With the cavesson you can influence the head and spine of the horse and the stelling and bending to the left and to the right.
You can see that the bending of the horse works through its entire spine, and that the hip on the hollow side of the horse comes forward.
Stelling is the placement of the head in relation to the first neck vertebra.
Bending is the lateral bending of the spine from the first neck vertebra (atlas) to the vertebrae in the tail.
Teaching the exercise to the horse
The horse must remain standing still while asking it for stelling little by little. When the horse takes the stelling and relaxes, you release the pressure and reward the horse.
When done correctly, you can see that by asking stelling, the horse bends through the neck its entire body. This results in a forward movement of the inside hip.
