Minecraft wiki entry for Wolf, associated text: A wolf becomes hostile to a player or other mob that attacks it unless the attacker is the wolf's owner, or is otherwise on the same team, or if killed in one hit‌[JE only]. It also causes wild wolves and standing tamed wolves in a 33×33×21 cuboid centered on the attacked wolf to become hostile to the attacker, allowing coordination for attacks and team hunts (only in wild wolves).
