Fire gutted a trailer home Thursday morning along Spring Street in Springdale Township.
Crews were dispatched to the fire about 11:15 a.m., said Allegheny Valley Assistant Fire Chief Jay Zangrille. It took about 25 minutes for firefighters to knock down the fire.
No one was in the trailer at the time, he said.
A dog died in the fire, said Abigail Gardner, Allegheny County spokeswoman.
The fire’s origin and cause remains under investigation, she said.
The man who lives in the home is being assisted by the American Red Cross, Zangrille said.
“At this time, we’re just waiting for the fire marshal to do their investigation,” Zangrille said.
Crews responded from multiple departments, including Oakmont, Allegheny Valley, Dorseyville, Rural Ridge, Blawnox and Lower Valley Ambulance Service.
