NASHVILLE, Tenn. - The Nashville Fire Department welcomed its newest members, including a certified arson dog.
The 2-year-old yellow lab named Spencer is a certified arson dog, who can help sniff out problems.
He's been trained to sniff out materials that can help start fires.
Arson attorneys say he's a big help in cases that don't have a lot of physical evidence left. Spencer will work with human investigator Mark Sells.
More than 400 arson dog teams work in the United States and Canada.
