In minecraft, my horse started to wander off to one spot?

Added (1). I know I can tie it up, but I just want to know why it always goes to that one designated spot.

Fence it?

Kill it.

A horse is a CPU. You can't exactly control it.

UPDATE:
After seeing the update, I got it. In the new 1.8 update, there have been many bugs with the animals, so I recommend fencing or trapping it.
