Unexpected or "All of a sudden" Horse Behaviors

 I find 95% of folks misuse a round pen, whether under the guise of "exercising," lunging or teaching the horse conditioned responses.

Let's use the example of learning to face the human and be caught. So many of the videos and real life scenarios I see of folks "working" the horse in the round pen, whether they are a professional or not, are incessantly "driving" the horse's movement with flags, whips, sticks, ropes, etc.

Unexpected Horse Behaviors

 No. It wasn't "All of a sudden..."

Horse behavior is not random.

You may have missed the subtle warning indicators in the animal's behavior and communication.

The physical responses reflect his mental and emotional state. 

The unwanted, resistant, avoidant, or even dangerous movement are the symptoms.
