This title is presented with a new introduction by Andrey Kurkov. A rich, successful Moscow professor befriends a stray dog and attempts a scientific first by transplanting into it the testicles and pituitary gland of a recently deceased man. A distinctly worryingly human animal is now on the loose, and the professor's hitherto respectable life becomes a nightmare beyond endurance. An absurd and superbly comic story, this classic novel can also be read as a fierce parable of the Russian Revolution.
