No, you will never be able to ride your wolf.
And there are only 2 shapes of your wolf < level 40 and > level 40
If you see a picture of another shape of a wolf (with shields at the side) then that's a European monster.
We don't have any clue on when Europe will be implimented in iSRO (International SRO)
Hope this clarifies
