Writer Ceiridwen Terrill writes about how, at a particularly sad and frightening time in her life, a wolf dog was the kind of companion she was searching for. In her book, "Part Wild: Caught Between the Worlds of Wolves and Dogs," she talks about an animal who's heart is divided between the woman she loves, and the desire to roam free. In the end, Terrill realized she must confront the reality of taming a half-wild animal.
