Pets after re-entering the world cease to be tamed. This applies to wolves,cats and partially parrots. The wolves as it were tamed, but belong to an unknown player and therefore the player cannot give commands to them and they not teleport to you.Popugai can sit on the shoulder, but not teleport.I hope you solve this problem. P. S  I play on the PC and this bug works in survival. Version beta 1.13.0.9
