Summon your pet and put equip on it. When you unsummon it the equipement stays on it and when u re summon your pet its already equipped. Today, i wanted to transfer my great wolf to another char, the equipment isnt on wolf anymore and not on the char that had the wolf, and neither the one that has it now... I lost expensive wolf equip now...
Solved.
For people who had this issue, trade back the pet to the initial character who had it and re summon your pet, the items should come in your inventory, however i strongly suggest you to go in a place where there is no people and get ready to pickup in case...
