i can see maybe her a lola getting along? though i will point out that in all of lola's years as a wolf, she has very little care or trust when it comes to witch's. atm she's semi friends with one but that's just out of arm's length for her to mentally handle. she had bad luck recently of a witch taking control of her, manipulating her to the point that she shifted without the full moon. if keira is willing to work with her then, lola would be a faithful companion for her.
but then i have elisa, who is a vampire and if you've ever seen true blood she is this place's bill comptom (mostly from season 1 and the end of season 7). she deals blood to the vampires in portland, mostly as her way of curbing the deaths that vampires tend to cause. she is kind, compassionate, big old fat soft heart and enjoys the company of humans unlike most of her kind. so you can both or either, i'll leave that up to you!
