When my horse eats he picks up his right foreleg and will press it against his body. Then he'll act like he's going to put it down but will keep it against him.
I was desensitizing him one day and I had put some feed bags on the ground so we could practice walking over a "tarp". He was fine when I led him over it so I started riding him over it. The first time he went over it he stopped directly on the bags and started to paw at them. All the bags were messed up before he continued over them. He was fine with walking over the bags for the rest of the lesson.
