He was not respectful during feeding time. After some work, He waits respectfully for me to put his food down and leave, and then he'll approach and eat except he paws while he eats, he will pick a front leg up and hover it above the ground swinging it around, then stomp, and repeat until he's finished eating. I it is always the same foot, his right front, and he does it all the time. If we are riding before dinner, and I ask him to stand still somewhere near grass, which is almost everywhere, or the barn, he strikes the ground and does his hovering thing. He minds but rather unhappily you ask me. If I stop him in the outdoor arena, indoor arena, or on the road he doesn't do that, its only near grass or near the barn. When he tries to graze while being led or rode, I say NO, and then he goes into pawing, stomping and swinging his leg around like it was in a sling.
What is he doing it for? Is he being impatient? Is it a dominance threat to me?
