In this photo, I see Jalila. Her head is up, but not raised in alarm. Ears are forward but not pricked. Eyes open, but not stary and wide. Her muzzle is soft, lower lip protruding and nostrils relaxed, not flared. This is a perfect picture of a horse that is interested and engaged, enjoying our walk out in the fields.
I posted my thoughts to my CT journal and Megan, a CT coach, added to them saying: I notice that the line of her mouth is quite straight, that although not flared, her nostrils are raised, and I see the shape of her eyebrow is pull forward and up very slightly to create a slight triangular shape and a crease. These would fit with the context of her alerting to something of interest while on her walk.
I love tuning in to the subtleties of horse communication and am blessed by having Jalila as a teacher. Her limited experience with humans and trust in me allows her to be be more expressive than many horses.
On we go!
