Code: "Mum is in the vicinity!!!!"

It always amazes me the language of smell. Pups can be fast asleep, but Mum arrives and just pops her head over the whelping box. Within seconds her scent is picked up by the pups smell receptors (remember at this age, even though their eyes are open, they cannot focus their eyesight until around 28 days). A message is then sent to their brain along the lines of "Code Mum is in the vicinity!!!!" They follow their nose. Smell is their primary sense, fine tuned in their first month of life and will remain their primary sense for their lifetime.
