It happened at the Queensbridge Houses at 21-01 12th Street in Long Island City.
The newborn was found inside her apartment with the family's German shepherd just after 6:30 a.m.
The girl's mother told detectives the baby was sleeping between family members when the dog climbed into the bed and bit the girl's face.
The baby was pronounced dead at the scene.
Neighbors say the baby's mother was visiting her mom at the apartment and wasn't home at the time of the incident.
They also said two big dogs, including a pit bull, were inside the apartment. Neighbors say they have made numerous complaints against the residents and say untrained dogs are a growing safety concern in a community filled with children.
Councilmember Julie Won released a statement about the child's death and said the dog was removed from the building.
Few other details were released.
