Lifting a horse’s hoof is an art form.
It is a process getting the horse to remove it’s foot off of the ground, because this is the horse’s main point of stability.
The horse has to trust you.
In order to gain the horse’s trust, you have to use a gentle approach. You have to give the horse time to adjust it’s weight. If you try to force it or frighten it, the horse will not cooperate with you. It will become stubborn and resist your attempts to control it.
People are kind of the same way.
The more you push, pull, shout at or prod a person, the less likely they are to cooperate with you.
Step back for a moment and consider why your horse may not want you to handle its hoof.
Then try a more gentle approach.
