The Minnesota Department of Natural Resources will be sniffing out zebra mussels this weekend.
For the first time, it's using canine teams in the effort to combat the spread of aquatic invasive species.
Conservation Officer Travis Muyres (Meyers) says three dogs have been trained to search out the mussels, much like dogs used in drug investigations.
Minnesota's mussel dogs will also be trained in tracking, firearms and wildlife detection.
