Some mixed breed dogs have the best noses. We had, for many years a mixed breed boxer. That dog could "smell you think". Once I took my wife's car to the tire shop for a slow leak in the right front tire. I came home & parked her car on the carport & let the dog outside. She ran straight around to that right front tire & smelled the tire all over !!! I think she would have made a good "drug dog".
