Thanks to the further development of the science of animal behavior and the special interest of scientists in the behavior of domestic dogs in the last 10 years, cynology is experiencing its rebirth. New trends, in which there is no place for violence, are gradually replacing the old ones. This brochure presents the main ideas of canine science at a new level. The “Controversial Issue” series, from the height of modern scientific knowledge, presents a new look at important, but sometimes heated debate issues. The books we publish talk about the perception of dogs, their methods of communication, and our mistakes in handling with them, about methods of education and communication based on social contact. The books are based on the results of studies of dog behavior at the end of the 20th - beginning of the 21st centuries. All our books are a single whole. If you put together all the information presented in them, you will get a single picture of the modern view of the dog. To obtain all the necessary information about the dog at the level of everyday communication, the reader will not need much time, since all the information is presented very compactly. Our program is a significant contribution to the protection animals, based on the study of their abilities and needs and the creation of ways of interspecies communication between humans and dogs.
