Re horses' brains or lack thereof: I was once hit in the face by a horse whom I was leading along a fence to a water trough. This was his own paddock, presumably well-known, but he forgot that the fence was electrified and brushed into it! I hadn't known anything about it! ARRGHHH, IT HURTS, MUST ESCAPE, THUDS INTO HUMAN, AWAY...

One loosened tooth later...
