My horse has recently started pinning his ears at what seems to me an odd time - when I turn him out, after I shut the gate and latch it. I am on the other side of the gate when this happens. Wanting some opinions on what this could be in response to, as the timing of it doesn’t make sense to my human brain.
His routine, feed, work, stall, turnout situation etc has not changed in years, and in fact he is doing better than ever generally, including under saddle. He doesn’t pin his ears during handling, saddling, riding, working around him in his stall, etc. He doesn’t pin ears when I dump feed (and is in fact pretty respectful at meal time and gives me space when I go in to dump feed or put treats in his feed tub).
The first time it happened, I turned him out as usual, took off his halter, gave him a pat etc, stepped outside the gate, and was looking down to latch it and I heard this squealing commotion and noticed that he was right up against the gate looking at me with ears back tightly. I was looking down at the latch when it happened so I only saw movement in my peripheral vision, but it seemed like he actually jumped up and down / threw a fit. I was shocked as this is unlike him but just stood calmly and from the other side of the gate tossed the lead rope of his halter at him. He stepped away, circled back and rushed back to the gate with his head up and ears back (!). Again, I calmly tossed the lead rope at him and he backed away. Then I stood and studied him a bit, and he walked up again, but nicely, and stood with his head over the gate and a soft expression. So I stood with him and scratched his cheek a little, said good boy, and then left.
Then it happened again. The other day after the usual grooming, riding (great ride), bathing, hand grazing, fly spraying routine, during which he seemed his usual self (no grumpiness at all) I turned him out and same thing. I took him into his turnout, took off his halter, and he walked over to his trough for a drink. I then stepped outside, shut the gate, latched it and there he was again - right at the gate, ears pinned, head up, looking at me.
I did the same thing as last time (tossed rope at him) and he stopped the ear pinning and walked away from the gate. Then he wandered off.
My first thought is that he is frustrated at being turned out, although nothing has changed about his turn out in years. But I would think if he is upset about his turnout, he’d pin his ears going into the turnout.
How would you react, and what would you make of this, if anything? It is very uncharacteristic behavior, and I guess I’m surprised to see my horse look so angry.
