So I've noticed something different on Bedrock Edition. A skeleton will usually run away from a wolf when it is chasing them, but once the wolf attacks the skeleton, they will fight back with their bow and arrows. I am not sure if this is a bug or it was intended for BE, because on Java Edition, skeletons just run away the whole time even if the wolves attack them. I am also unsure if this is planned to be fixed in a future update but I just wanted to share it on here to make sure someone knows.
