while there are those who feel they have an animal spirit or a strong connection with a particular animal [Therianthrope] no one can physically shape shift into said animal. you were born a human and that's it. 'real werewolves' [again, Therianthrope] are spiritual, not the mythological beasts from fantasy.
i have been told werewolves are astral beings. if this is true, you could try calling upon them in your spells and rituals for energy, much the same way one would call upon a deity. plus our society makes stuff for everything, so you could get a werewolf tarot, werewolf goblets, candles, and many other things to decorate your altar with. if your animal isn't a wolf, then go with whatever creature you're connected with.
