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.
The presence of the mother is thus favorable, even necessary, for the development of appeasement-submission rituals and for the puppy's hierarchization in the adult pack. Lactation wanes around 7 to 10 weeks. From the age of 5 weeks the puppies begin to growl to gain possession of their food.
