When Chato's barking didn't stir Jerrica Seals, the recently adopted dog triednibbling on the teenager's leg, to get the girl out of her burning house.

No one was hurt. Fort Myers firefighters responded at about 7 a.m.

Five people lived in the Garcia home. That was neighbor Janice Hamilton's main concern when she looked out of her window Friday and saw the flames. "I just threw my pants on to run outside and make sure  they knew how many people lived there," Hamilton said. "It was scary."

"Seals called me screaming," said Leticia Vega, 36, the sister of Seal's boyfriend, Javier Garcia, 23, who owns the home. "She said the dog woke her up barking, jumped on the bed and bit her on the leg."

It is said that Garcia's brother brought Chato home several weeks ago after the animal wandered onto a Lehigh Acres construction site. Since then, Vega said, Chato had been mostly quiet-until it mattered. "He doesn't usually bark." Vega said. "He's real friendly."

According to deputy fire chief Steve Clyatt, possibly the fire started because of an inadequate extension cord used on a window air conditioner. More than half of the home was burned down. There was extensive smoke and water damage in the remainder of the structure. Estimates for repair costs were unavailable. "I'd say it's unlikely they will recover this, but I've been surprised before," Clyatt said.

A. Janice Hamilton Helps Save Neighbors

C. such a bad fire was seldom seen      D. Chato is a very clever dog
