A Dogs Heart = Собачье сердце

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