What does Warwick Schiller say about the difference between a horse that is with you and one that is just near you?

Warwick Schiller's distinction between a horse that is with you and one that is simply near you is one of the most important concepts in his teaching on connection and relationship, and it directly addresses what many handlers mistake for a good relationship when they actually have a physically compliant but mentally absent horse. A horse that is near you is physically in your vicinity. It stands tied to your trailer, it walks beside you on a lead, it stands in the crossties while you brush it. But its attention is somewhere else — it is watching other horses, monitoring the environment, looking for the next stimulus. It tolerates your presence but is not interested in it. This horse is not a safety or handling problem in most situations, but it is not genuinely connected either, and in stressful or novel situations its attention will follow the environmental stimulus rather than the handler. A horse that is with you is in your vicinity and has chosen to be there, with its attention genuinely on you. It notices when you move, responds to subtle shifts in your energy and posture, and in uncertain situations looks to you for information about how to respond. Schiller describes this quality as the horse's attention being on the handler rather than through the handler — the handler is not something the horse is looking past to find interesting things, but is itself the interesting thing. Schiller teaches that developing a horse that is genuinely with you requires becoming genuinely interesting and reliably calming to the horse — two things that cannot be forced but that develop through the quality of interaction over time. He recommends testing the with-you quality by moving in unpredictable ways — a direction change, a stop, a crouch — when the horse is at liberty and watching whether its attention tracks your movement or stays fixed elsewhere. A horse that follows your movement at liberty is with you. A horse that stays where it is regardless of what you do is near you.
