Slight twitching of the tail along with simple nods are part of a horse’s body language which indicates its calmness. If a horse wants some space for itself, they lightly swing their tail. If you want to communicate with your horse, make sure your own pitch matches theirs so that you may resonate with them.  Also, try to copy their gestures because this will help them familiarize themselves with you. All these efforts also develop trust with the horse. They also show their emotions using extreme body language. For example, if the horse starts fidgeting, it might not like where you are taking it. If you work on the bond, you will notice your horse looking out for you. It will pay attention when you are concerned and will also communicate its love towards you.
