Even after completing the trophy "Leader of the pack" (tame and befriend five wolves) the wolf mask headwear you can unlock upon completing this trophy has not unlocked on my profile, this also seems to be an issue for many others as well as friends and players on YouTube. Despite me uninstalling Minecraft on my ps4 and updating it to the newest addition, this does not resolve the issue. The trophy is defiantly complete as it was done so back in 2014.
