I think that they should have a few unwanted actions if they are sitting too long, for instance they could dig holes in the ground (if they are near dirt), they could mess up a garden or farm (if they are near one), they already bark alot..., and my favorite is if placed near wool they could turn it yellow by marking it.
all these behaviors should be stopable by right clicking on them
