First off, do not get me wrong, I do like wolves. But I hate wolf-a-boos.
I did some reading on wolves, and wolves do attack humans for no reason at times. But most of the time wolves avoid human contact as much as they can. They will even sometimes abandon their kill, if humans are around. So there is no possible way "you can have a random wolf pet from the woods". Wolves do surplus kill, they urinate on each other (domination thing), and smell like pheses. They're all around, gross xD Yes they are pretty and adorable, but really. Their not gods. Wolves are just as vicious as coyotes, lions, hyenas and any other wild animal that reacts on instinct.
Theyre just animals, I promise they are nothing different than any other animal in the world. And I would say the same thing about coyotes. xD So.. Enjoy :]
*And another thing, to be serious about a spirit animal or past life is something you need to be real with. Finding your spirit animal and exploring past lives takes A LOT of meditation. I found my spirit animal, although I havent explored much of any past lives. So its nothing against people who seriously have the spirit animal of a wolf*
