Unable to Equip Wolf Armor

 Currently tested equipping Wolf Armor on the Realm I play on with a few other friends and small Youtube creators. Was not able to do so. I created a new Creative world and spawned in a Wolf, fed it a bone to tame it, then successfully equipped the Wolf Armor to the Wolf. Unclear why I couldn't on the Realm. The Wolves will just stand or sit down when right clicked with the Wolf Armor on the Realm. First time I've submitted a Bug Report. Hope this is enough info!
