"Heart of a Dog" by Mikhail Bulgakov is a satirical novella that tells the story of a stray dog in Moscow who is transformed into a human being through an experimental medical procedure. The dog, named Sharik, is taken in by a well-meaning but eccentric professor who hopes to study the effects of the operation on his behavior and personality. As Sharik adjusts to his new life as a human, he struggles to reconcile his canine instincts with the expectations of human society. Meanwhile, the professor's colleagues and acquaintances become embroiled in their own power struggles and petty rivalries, leading to a series of absurd and farcical events. Through his portrayal of Sharik and the human characters around him, Bulgakov offers a biting critique of Soviet society and the dehumanizing effects of ideology and bureaucracy. "Heart of a Dog" is a powerful work of political satire and a testament to Bulgakov's skill as a writer.
