We tend to think that faces of people and snouts of horses are symmetrical, but the pictures below show that they are not. In fact, they are sometimes very asymmetrical.
The right and left sides of horse’s snouts and nostrils can differ in size and shape.
It’s also interesting how much the right and left sides of people’s faces can differ. In this picture an image of a painted face is divided in such a way as to create three faces: one that is made up only of the right half of face (right picture) and another that is made up only of the left half of the face (picture in the middle). The original image appears on the left:
All horses and humans are in fact born asymmetrical. The perfect symmetrical horse or human is yet to be born
Not only are snouts and faces asymmetrical, but the whole body and limbs are also not symmetrical. Just like every human, every horse is for example left- or right handed, both in the frontlegs and the hindlegs. Also, the horse is bent to the left or right in its body and it carries more weight on the frontlegs than on the hindlegs. This causes an uneven distribution of the weight over the four legs. When the rider does not recognise and correct this imbalance, this can lead to leg and back problems.To prevent these problems the horse needs straightness training.
Every horse is unique and needs tailor-made straightness training if he has to carry a rider. The goal of straightness training is to develop the horse symmetrically in body and limbs so that he is able to carry the weight properly.
