                 Strikingly, dogs do not make mistakes,
            despite the countless number of scents in their
            world. They are easily able to distinguish the
            particular smell they are looking for.

            Experiments have shown that a trained dog is
            able to locate what was expected of it from
            among items covered with highly pungent
            skunk scent.  67
                 The Schlieren photography technique re-
            vealed that dogs used a different method of in-
            halation: a dog smelling something twitches
                                                            A photograph showing
            its nose when exhaling, and the air heads di-
                                                            dogs’ inhalation and ex-

                                                            Schlieren technique.
            Thanks to this special design, the dog’s ex-
            haled air flows in a different direction, and the
            air in its breath is thus prevented from combining with the scent.  68
                 Researchers are still trying to develop new devices by unraveling the
            complex analysis performed in the canine nose and brain.  69  There is pres-

            ently a great need in the day for such devices, especially for detecting
            bombs, mines and various dangerous substances. However, the devices
            that have been produced so far come nowhere near matching the scent
            sensitivity of dogs.


                 Scent Perception in Fish
                 Scent perception is important to just about all fish species.  70  The
            scent perceiving region is located on the rear surface of their noses. They
            find food by following scent molecules dissolved in the water. In addition,
            their sense of smell warns them of danger: Fish that detect the smell of an
            injured fish immediately go on the alert.
