Allowing a horse to sight see, is very poor training on behave of the rider, Why, would I say that?
Consider the facts:
- Horses have amazing peripheral vision with two blind spots. One blind spot is directly in front of his nose extending around four feet in front of it. The second blind spot is behind the tail. That blind spot extends about ten feet long, beyond the horse's tail.
- The field of view for horses can reach up to 200 degrees.
So why would you let a horse sight see, they can see everything they need to see with their head straight ahead. All allowing them to turn their head to sight see, does, is teach them to NOT pay attention to the rider. Eventually, the sight seeing will get the rider into trouble. An in attentive horse will eventually start taking control and sooner or later do as it wants and the rider will not have a choice in the matter. And we wonder where the outlaws come from, we, the humans, made them that way.
This might seem like such a trivial thing to a lot of folks, but it is the trivials, one step at time, that ruins good horses. We need to understand "the nature of the horse" in order to co-exist with them and keep control. Once out of control, the road back, is full of large mud holes, that sometimes can not be filled.
Haven't you ever wondered, why the dead broke, very well trained horse, becomes too much for the rider to handle. One little trivial after another, and the horse responds accordingly. We retrained them to NOT be the dead broke, do anything, go anywhere, equine, we started with.
