Dog sniffs out mold problem

When Paul Hewitt wants to check whether mold exists in a home or building, he brings along his two-year old beagle, Kody. That's important because Kody does the work. When Hewitt says "show me," she sniffs out the mold by pointing her nose at the spot and sits patiently at the spot, nodding her head up and down, until the spot is marked. Kody has been trained for up to 1,000 hours on detecting 18 different types of mold.
