A fire at a south San Antonio home sent two firefighters to the hospital and killed a small family dog.

The fire broke out just before 4 a.m. Wednesday in the 200 block of Felps Boulevard.

Neighbors reported hearing an explosion before the carport and part of the home went up in flames.

A man who lived in the house made it out first through the front door. Two San Antonio police officers attempted to go inside and find man's girlfriend, but said there was hardly any visibility due to heavy smoke.

Officials said the woman managed to crawl through a window to safety and suffered minor cuts.

An electricity service line reportedly broke and began to arch in the back of the home. Two firefighters were shocked while battling the fire, and taken to the hospital for treatment.

"They bumped up to the refrigerator and got a little shock. One of them had a pretty good shock to his right arm, and he could not use his arm for a while, but they're fine," said Capt. Eusebio Perez, acting battalion chief for the San Antonio Fire Department.

Several poodles inside a shed behind the home made it out safe, but a Chihuahua died in the fire, officials said.

Arson was called to investigating the cause. Fire officials initially believed it may have been electrical.
