Another heroic deed of dogs. They sniff out human-killing molds.
Research at Alabama's Auburn University seems to back up her claim. Scientists at the university's Canine and Detection Research Institute found that dogs can detect a scent that is only present in 1 part per every 2 billion air parts.
Another bonus with the dogs, Rasmussen said, is speed.
"It can take weeks to get test results back from a lab," she said. "We can go in a house and tell them that day if they have mold or not."
