Christoph T. M. Krause, lives in Cologne. He has been running his own successful dog service company since 1998. From his wealth of experience in observing the dogs of his own family and in his daily walking and boarding business, the question arose why both the dog and (his) human, and both together, develop RITUALS? Krause collected numerous examples from other dog lovers and created an exciting narrative of a thousand-year-old symbiosis between dog and human.
