A Dogs Heart = Собачье сердце

The novella by Mikhail Bulgakov «Sobachye serdtse» is a work about the loss of civilized values in Soviet Russia, combining sharp satire and profound philosophy.
An outstanding surgeon conceived an unprecedented experiment — an operation to transplant the human pituitary gland and testicles from a stray dog named Sharik. The results of the operation exceeded all expectations — Sharik gradually began to take on human form but became a boor and a drunkard. Under the influence of the communist activist Shvonder, who instilled in him that he was a proletarian suffering from the oppression of the bourgeoisie (represented by Professor Preobrazhensky and his assistant Doctor Bormental), Sharikov turns life in the professor's house into a nightmare.
The novella is published in an English translation by Antonina V. Bui.
