Sobachye serdtse) is a black-and-white 1988 Soviet comedy-drama science fiction television film directed by Vladimir Bortko.

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 doctor implants a pituitary gland and testicles of a recently-deceased alcoholic and petty criminal, Klim Chugunkin, into Sharik.

After his transition to human is complete, it turns out that he inherited all the negative traits of the donor (bad manners, aggressiveness, use of profanity, heavy drinking), but he still hates cats.

He picks for himself the absurd name Poligraf Poligrafovich Sharikov, starts working at the Moscow department for extermination of stray animals and associates himself with the new Bolshevist building administration, who strive to take away part of doctor's big apartment (an ongoing sub-plot of the film).

In a documentary about the film, the cinematographer recalls that when he asked the director for the script, Bortko simply gave him a magazine with the text of the novel.
