- We all give off cells, gasses, and vapors.
These cells and odors act like smoke. So dogs, who have 44 times the
sniffing power of humans, can pick up the scent and follow it.
- A much larger part of a dogs brain
is devoted to processing smells than yours.
- Dogs can be trained to ride in anything
from helicopters, trucks, and boats, to sling harnesses and chair lifts.
- Some search dogs locate people buried
under the snow of avalanches, search for evidence in crime, and find
people in the water.
- Cloudy days, mornings, and evenings are
the best times for dogs to search.
- Dogs navigate in brush better than humans.
- Depending on the conditions, dogs can
pick up a scent up to a half a mile away!
