San Diego Fire Captain James Shadoan is better known to fellow fire fighters as "Emily's handler."
3-year-old Emily is one of just 52 dogs in the United States capable of solving an arson investigation.
"Emily is actually solving crimes across the nation, I mean legitimately has broken some cases, " said Rachel Laing, Board of Directors of the San Diego Fire Rescue Foundation.
Emily flies all over the country with Shadoan. In San Diego, she tipped police off in their search for a man setting homeless on fire last summer.
So how does she do it?
"The only way she eats is out of my hand, 100% of the time and when she trains," Shadoan said.
Emily has never eaten from a dog bowl.
