FIRST CRITICAL PERIOD
(Birth through three weeks)
NEW ACTIONS AND REACTIONSThe pup has reflex responses only to hunger, cold, touch and even elimination, which is created by the mother's massage and lapping. Pups will "pig pile" for warmth. Pup whines and cries. Swings his head from side to side. Can crawl forward and backward, but does not venture out of the nest. His eyes will open between 10 and 19 days of age, however he cannot see. He does not follow moving objects and does not startle at rapid movements. Around 18 days he may get up on wobbly feet and walk. |
