Undeniable Solidarity

Undeniable Solidarity tells the story of our long partnership with dogs from the first friendly wolves who guarded our sleep during the Stone Age to their roles today as our best friends, trusted and joyful pets, and their service as therapy, detection, and rescue dogs.

Dogs and humans have lived together for thirty thousand years, and they have changed us as much as we have changed them. Based on author David Hagner's work as a rehabilitation counselor with therapy and service dogs, drawing on information from archaeology, world mythology, sleep science, dog behavior, and philosophy and enlivened with stories of the role dogs have played in the lives of famous historical figures, Undeniable Solidarity revolutionizes our understanding of the bond between dogs and humans and gives us a deeper appreciation of our partner species.
