Yes, it is very true that horses can sense fear! Their survival depends on it as prey animals! Anything that you would perceive as agression is usually fear, such as kicking, rearing, biting, running away, etc. Constant tail swishing and a horse holding their head up high can also be signs of fear. We can help them be less fearful by being good leaders for them. Their responses to our leadership is one way we teach. Their reactions to our fear or anger, etc. is like a giant biofeedback machine so also a great teaching tool!
