Your dog is always pulling on the leash? Relaxed walks are im-possible? You are not alone! The little terrier Bertie has simmered a strategy how the unnerving (for both parts!) jerking and retching can be exchanged against cheerful walking on a loose leash. In this book he explains in his frank, but friendly and hu-morous manner how to relax both the leash and the atmosphe-re. In his human’s dog school, he has already helped hundreds of owners to get their arms pain free. Funny, entertaining and highly effective!
