Why Everything With Horses Is Done From The Left

Ever wonder why everything with horses is done from the left? Starting every task from the left-hand side of our horse’s has been drilled into our routine ever since you have began to ride or handle horses. Leading from the left. Tacking up from the left. Grooming from the left. Although we carry out this routine, have you ever stopped to wonder why everything with horses is done from the left?


Horses have monocular vision, as their eyes are placed on the side of their heads. Monocular vision means the horse can see either side, but not directly in front of them. Therefore, approaching and standing to one-side of horse’s is beneficial to allow them to have an adequate view of you and what you are doing. As they can see you properly, they can assess whether you are a threat or not, and what to do next. So, why do we choose the left field of view?

The left-hand side is the natural preferred field of view for the horse. Studies in feral horses have shown, from a foal into adulthood, there is a preference for left-eye vision. Therefore, starting all tasks from the left aids the horse in achieving the left eye-vision.


It is also suggested the left eye’s visual field is important to the horse’s social responses. Information collected by the left eye will be sent to the right side of the brain. The right side of the brain processes recognition of familiar faces and expression. Therefore, seeing on-coming items, people, or horses, through the left eye helps the horse decide whether they are a threat or not. Horse’s have been shown to be able to relate facial expression to positive and negative outcomes, therefore approaching with a positive facial expression may be help when carrying out new or strange tasks, or even just catch to your horse!

Approaching and carrying out task from the left-hand side may also be of benefit to the horse and owner bond. Research has shown that bonding behaviour between mares and foals most commonly occur on the left-hand side. Therefore, carrying out grooming and handling to the left could improve the trust and partnership between you and your horse.


It must also be considered that the industry is set in its ways. Everything is done from the left and has been for numerous years. Therefore, the likelihood of your horse being handled from the opposing side is slim. This means your horse will probably be more comfortable with activities undertaken from the left-hand side. Stress increases learning time, so handling from the right-side may hinder performance when training from the ground.

However, this does not mean you should neglect the right-hand side completely. Although it may be more challenging to carry out tasks from this side at first, slowing introducing routine from the right will be beneficial. Improving trust and co-operation from the right could prove important in emergency situations and training. Nonetheless, it may be easier to start new tasks from the left at first.
