A Puppy's Life to Dog-dom. Weeks 1 and 2. These weeks are very quiet in that the puppies can not see or hear for the first 10 to 15 days, they can not regulate their own body temperature - they are totally dependent on their dam and their environment for warmth, nutrition and stimulation.
Newborn puppies are born with their ears and their eyes sealed shut. Puppies lack two senses at birth: sight and hearing. It takes a minimum of 10 days to two weeks for their final two senses to develop. Although lacking their sight and hearing might seem odd to human beings, puppies develop in a way that is advantageous to their species.
