Portrait of Marie-Zephyrine (1750-55) of France with her Dog Jean Marc Nattier

The picture has something of this: people, child, baby, son, woman, girl, portrait, seat, two, furniture, dress, sit, reclining, family, room.
Perhaps it’s a painting of a young girl in a white dress with a brown dog sitting on a blue cushion in front of a gold and white drape.
