Protected Rooms

An Ordered Household
Space and Routine
Professor Preobrazhensky's apartment contains separate rooms for work, patients, meals, and rest. Its routines represent both professional competence and a defended private life.
A Fragile Refuge
Sharik's welcome into the household initially seems to enlarge its comforts rather than threaten them. The arrangement depends on the professor's authority and the residents' cooperation.
The Committee's Demand

A Dispute Over Rooms
Occupancy Pressure
Shvonder and the house committee demand that Professor Preobrazhensky surrender rooms to meet a housing target. The professor counters with an occupancy exemption and threatens to close his practice.
Temporary Victory
A telephone intervention forces the committee to retreat. The episode protects the apartment for the moment while making clear that its security depends on authority beyond its walls.
Domestic Disorder

Strain in the Flat
Daily Damage
Sharikov breaks household objects, chases cats, causes a flood, and ignores rules. The staff repeatedly mop, repair, and manage the consequences of his behavior.
A Household at Work
The episodes turn private space into a scene of continual crisis. Professor Preobrazhensky's orderly home can contain the damage only by exhausting those who live and work there.
Claimed Living Space

The Thirty-Seven-Square-Foot Claim
New Leverage
Sharikov uses his registration papers to claim an entitlement to living space in the apartment. A private experiment has acquired a public and bureaucratic dimension.
The Home Divided
The claim gives him a formal basis to resist the professor's authority. The apartment's earlier disputes over occupancy now converge with the personal conflict between creator and creation.
Quiet After Violence

A Restored Interior
The Search
Police arrive to investigate Sharikov's disappearance, placing the household at risk of arrest. Professor Preobrazhensky insists that the dog Sharik is alive and asks the visitors to see him.
Uneasy Calm
The investigation ends without exposing the full transformation and restoration. The apartment returns to warmth and quiet, although its domestic peace rests on a concealed, extraordinary history.
