Everyone should be able to read: there would be fewer problems with large and small dogs! Here in Switzerland, the courses with dogs are required (for all) and it's a behaviorist our kennel club who advised us. This is a great book each page has a picture with a dog attitude, explanations, advice. It is clear, interesting and it really helps in everyday life to understand, was to avoid conflict. Recommended for course dog lovers but also for those who are afraid or do not like: one sees more of the same way then. It's not a "big" book forbidding Bravo Mrs Rugaas! this is the book that is kept in handy, as one leafs regularly.
