In my recent game, it happened to me that I still have meat under my TC while a boar is coming in. I garrisoned the targeted vil and waited until I was ready to take it down. But the boar wanted to go back right away instead of staying in place for a little bit. So I had to keep a vil shooting it and kept dancing around to keep it there.
I recall the same experience in HD and it seemed that the boar tended to stay longer. I pretty much only had to dance once.
