Fort Dodge firefighters are on scene at a burning house at 1808 2nd Ave S. Black smoke could be seen coming out the windows as of 11:40 a.m. Monday.
Doug Ostbloom, the city fire marshal, is still investigating the fire.
"I was ever so happy to see Lulu come around that corner with the child," neighbor Brenda Hill said.
At about 11:30 a.m., her son saw black smoke coming out of the second story windows and called 911.
Hill and her husband then banged on the door to make sure no one was inside.
"I was like a psycho beating on the door," she said.
Lulu, one of three tenants, declined to comment.
Hill said that Lulu had been out for a walk with the child.
Lt. Mitch Halverson said there was no one inside at the time of the fire.
"It started somewhere in the kitchen area," Halverson said.
Firefighters do not yet know how the fire started.
Fire Chief Kent Hulett said that they were seeing if one of the tenants used the stove or oven today.
Neighbors said they thought they smelled wires burning.
Firefighters didn't know whether anyone was inside when they arrived, Hulett said.
"Our first priority is search and rescue," Hulett said.
