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.
