Err, I’m no expert, but my horse (Arab) had that capacity. He oh so gently tipped me over when I was squatting in front him adjusting his polos.
I looked him in the eye, and I’m telling you, he was laughing.
But in ops case, no it’s not a mental fake. I too vote for more turnout, hay, not grain and checking his environment for one full ordinary day.
Did they get a new horse that intimidates him and is walked this stall everyday? Is one of his handlers going through personal issues and inadvertently taking it out on the horse’s?
Anyone actively not like him? Etc.
