Rochester firefighters battled a house fire on the City's east side Wednesday night.
Crews were called to a house on North Union Street at around 8:45.
Officials tell News 10NBC a person was seen at the window of the house, but fled after people outside started yelling about the fire.
Firefighters rescued a dog from the second floor. There was no one else inside.
Officials say there is extensive damage to the back of the building, and the fire could have spread to a house next door.
The Red Cross was on scene to make an assessment.
