A new study in the journal Scientific Reports gets to the bottom of it: Why do dogs that are trained to locate poop sometimes find the wrong kind of poop?
It happens anywhere from 4 percent to 45 percent of the time, said Karen DeMatteo, a biologist in Arts & Sciences at Washington University in St. Louis. Her new research confirms that there are three viable, alternative explanations beyond errors in handler or dog training that can explain the collection of non-target scats with detection dogs in some ecosystems.
Detection dogs are trained to use scent, not their eyes, to locate specific kinds of scat. They’re useful partners in conservation projects as an alternative to camera photo traps or other more invasive means of identifying which individual animals are present in an area.
And while finding the wrong kind of poop doesn’t ultimately muck up research results — researchers who use scat to track animals usually use DNA tests to confirm the identity of target and non-target evacuators — collecting and testing false positives costs a project time and resources.
