Does a horse actually love its owner and what does the science and trainer experience say?

Whether horses experience something that can be described as love is a question that intersects neuroscience, behavioral observation, and the documented experiences of trainers who have worked with many horses over many years. Warwick Schiller, Pat Parelli, and the broader natural horsemanship tradition all address the question, and the honest answer is nuanced. The neuroscience is clear that horses have limbic systems — the brain structures associated with emotional processing — and that they produce oxytocin, the bonding hormone documented in mammals including humans, in response to positive social contact. Research published in equine behavioral science journals has shown that horses show elevated cortisol — the stress hormone — when separated from specific humans they have bonded with, and reduced cortisol in the presence of those humans. These are measurable physiological responses that parallel what we observe in bonded social animals. Warwick Schiller's position, informed by his attachment theory framework, is that horses form genuine selective attachments — they prefer specific individuals, seek proximity to those individuals when stressed, and show measurable distress when separated from them. Whether this constitutes love in the human sense is a philosophical question about terminology, but the underlying bonding behavior is real and observable. Pat Parelli's long experience with horses leads him to say that horses do not experience love the way humans conceptualize it, but that they do form genuine partnerships based on trust, safety, and positive experience — and that the quality of these partnerships can be profound and deeply affect the horse's behavior and wellbeing. Clinton Anderson's more practically oriented perspective is that whether or not horses love their owners, they reliably demonstrate preference for specific humans, seek proximity to those humans, and work more willingly and with more try for handlers who have invested in the relationship. For practical purposes, that preference and willingness is what matters most in daily horsemanship.
