In a natural or domesticated setting, each horse will respond differently to touch, sight, smell, sound and no two the same. The natural instinct or natural "flee", are what protected horses throughout the years while being in the wild.
Described many ways such as fear or and obstinate horse, it's because of their " life preservation", that is why horses do what they do.
Now the safest time to be creative and have fun with your partner is to set up for success on the ground, so allow your imagination to run. It's a wonderful way to heighten the trust level between you and your horse in a safe way.
