I've encountered this bug on previous versions as well: When I breed two wolves and get a baby wolf, I usually sit the baby down because I don't want it to follow me. However, if I go a long distance away, I've observed that when the baby grows, it teleports to me, seated. Sometimes, if I'm in a cave for example, I won't be aware that it teleported to me and then I will lose the wolf. This does not seem like correct behavior. The baby, once grown, should remain seated where it was before.
