Paul-Emile Victor masterfully draws portraits of animals, tells about the peculiarities of their behavior, shows the decisive role of sled dogs in the conquest of both poles of the Earth. Author's Prologue: "I Love Dogs . I love cats.... I love the wolves.... I do not like pigeons, because they, like people, are cruel. In dogs and wolves, the winner licks the surrenderer, and these birds, supposedly meek, beat the defeated with their beaks to death. And I also want to say that animals, especially dogs and cats, and especially sled dogs, are important and valuable to me, because I feel their closeness, affection, loyalty, courage, strength, help.
