Here we are at the end of the first week. Starting tonight in the early morning hours each puppy will be a full seven days old. This first week has been about growth and weight gain. That will continue and even accelerate as the next seven days will see MANY changes in development.
Still no personality differences–each puppy spends their time eating and sleeping. Still with eyes and ears sealed, blind and deaf, they seek their mother if they feel her nearby. Next week that will all change!
