Domestic dog
The Heart of a DogDomestic dog is the canine state in which the narrative closes, placing Sharik back in a life of domestic warmth after his humanization and reversion. The ending gives the dog his own inward perspective: he feels fortunate and at home, even as the operation that changed him remains present in memory as a troubling scene.
Identity and Setting
The dog lies stretched on the carpet beside the leather couch in Professor Preobrazhensky’s apartment. The grey, accordion-shaped radiators hiss gently, while the blinds shut out the night sky over Prechistenka Street. These details locate his comfort in the professor’s carefully ordered domestic space, where he has become a settled presence rather than an animal passing through.
His comfort varies with the day. In the mornings, March fog makes his head ache, especially around the circular scar on his skull; by evening, warmth eases the pain. The scar quietly records the physical history that his contented present might otherwise seem to leave behind.
The Dog’s Point of View
The closing passage grants the dog a private, directly represented train of thought. He considers himself very lucky and says inwardly that he is settled in the apartment. His uncertainty about his pedigree follows: he concludes that he has no Labrador blood and thinks his grandmother was not the refined ancestor he had imagined. The passage lets the dog assess his own origins in practical, irreverent terms, distinct from the medical and social judgments made about him by people.
That perspective is affectionate but not idealized. The dog acknowledges that his head was altered, then dismisses the matter as none of his business. His acceptance does not erase the operation; instead, it shows how far his attention has shifted toward present security, warmth, and belonging.
Memory of the Operation
The calm of the apartment is interrupted by what the dog saw that evening: the great roan professor searching through a jar for a brain, examining and slicing as he continued his work. The recollection is framed as terrible, a sharp counterpoint to the dog’s warm thoughts in the present. It recalls the human intervention behind his altered condition without displacing the domestic scene that now defines his life.
The professor hums the refrain about the banks of the sacred Nile as he sits, and later sings it while pursuing his examination. The repeated tune threads the settled evening and the remembered operation together: the same household sound accompanies both the dog’s comfort and the procedure that left its mark on him.
Ending and Significance
The ending returns the story’s attention to Sharik as a dog, but not to an untouched animal. His scar, morning headaches, thoughts about ancestry, and memory of the operation all belong to the canine life he now inhabits. At the same time, the carpet, couch, warmth, and sense of being settled make this restored state a form of ordinary belonging. The final perspective is therefore neither a simple medical account nor a verdict on the experiment: it closes on the dog’s own contentment, with the disturbing origin of that life still visible at its edges.
