Wisconsin dog sniffs out arsons

(CNN) - You know that dogs have got extraordinarily-strong senses of smell.

But you may have never seen it put to such good use as this. A very special pup in Wisconsin is being credited with helping to uncover vital clues in two recent fires.

When Moon finds a scent of any flammable liquids, he will scratch at it and sit down. He is a 6-year-old black lab. His value is estimated at $50,000.

"It's great to be part of that team," said Fennig. "Moon doesn't declare it an arson by himself. He's another tool that investigators can use.
