There has been a salutary tendency among the dog fancy lately to relate the man/dog partnership to the innate imperatives of canine behavior, possibly inspired to some degree by the work of Konrad Lorenz (who wrote a preface to this book) and Michael Fox whose book on care and training (Understanding Your Dog, 1972) bridged the gap between laboratory, field research and the dog owner's household. Mr. Trumler's kennels and house are noisy with dingoes, jackals, elkhounds, Alsatians and a slew of half-breeds, in order to observe more closely the range of endemic behavioral habits of semi-domesticated animals, and derive some enlightening explanations of the domestic canine's body language, social development, and attitudes toward man. ""A dog's first experiences of man are decisive"" -- and the owner should take advantage of the compact and efficient series of learning experiences undergone by pups in a natural family situation which trains them for pacific and cohesive group living (in which aggression plays a minor part). Man should take the place of the model older dog in the pack -- not be a tyrant. There are explications of baffling-to-irritating habits like nosing, pawing, varieties of tail-wagging, noises, etc. As for training, infinite patience is the answer.
