When writer Belinda Pollard acquired her spunky Australian Terrier in May of 1998, she had no idea in what ways the furry little hurricane would change her life - and herself.  In Dogged Optimism: Lessons in Joy from a Disaster Prone Dog, Pollard compiles the story of her adventure with bright-eyed, ever-inquisitive Killarney, and in her quietly humorous, heartfelt way she fills the pages of the memoir with the meaningful essence of dog ownership.  Through sixteen "lessons" Killarney teaches Belinda how to live fiercely and freely, while she, a natural-born worrier, warily follows Killarney's lead into the sometimes frightening joys of life.
