Dogs can still smell surprisingly well through snow. Snow is full of tiny air spaces, and scent molecules from animals, plants and other interesting things can travel upward through those spaces and escape at the surface. Bernoulli can easily follow the footsteps of a human through the snow, but even more wild is he can smell what walked through the snow BEFORE the snowfall! #bernesemountaindog #dogsinsnow #science #wintervibes
