Plot

The film is set in Moscow not long after the October Revolution. A complaining stray dog looks for food and shelter. A well-off and well-known surgeon and professor, Philipp Philippovich Preobrazhensky, happens to need a dog and, with a piece of sausage, lures the animal to his large apartment, used both for living and medical practice. The dog is named Sharik and well taken care of by the doctor's maids, but he still wonders why he is there. He finds out only too late that he is needed as a test animal. The doctor implants a pituitary gland and testicles of a recently-deceased alcoholic and petty criminal, Klim Chugunkin, into Sharik.
