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.
Some puppies should not be put on the electronic pet containment system until as late as five months of age or later. All puppies go through a fear imprint stage from approximately six weeks to sixteen weeks of age. Any thing that could psychologically damage a puppy during this time can affect it for life.
