Have checked horses on this. I knew a neighbor whose horse would not look guilty but would stay at the far end of the field sometimes.

Horses can absolutely look quilty. I always know when I walk in the barn which one has “disassembled” something in their stall. Instead of being at the door nickering, they hold their head down and “hide”. I don’t beat them or anything, just fuss at them.
