When a respected surgeon decides to transplant human body parts into a stray dog, he creates a monster - drunken, profligate, aggressive and selfish. It seems the worst aspects of the donor have been transplanted as well. As his previously well-regulated home descends into riotous chaos, the doctor realises he will have to try to reverse the operation; but the dog isn't so keen... Wild, uproarious and deliriously comic, Bulgakov's short novel is at once a comment on the problems of 1920s Russia and a lasting satire on human nature.
