    - relies on mother for suckling, elimination and comfort
    - most of the time spent feeding and sleeping
    - eyes and ears are closed and non functional relying on senses of smell, taste and touch
    - motor abilities are limited and reflex driven
    - vocalizing to alert or seek attention
  3. Transitional period
    - 14-21 days of age
    - rapid neurological and physical change period
    - opening of eyes at day 13 and ear canals between 18-20 days old
    - no longer relies on mom for elimination
    - more advanced motor movements
    - interact with the other puppies and might play fight or wag their tails
    senses mature and behaviours are more obvious
  4. Socialization period
    - between 3-10 weeks of age
    - onset of more adult patterns of behaviour
    - sensory and motor abilities are fully developed
    - gradually spends more time away from mom, spends less time feeding and sleeping
    - teeth begin to erupt
    - weaning around 7-8 weeks
    - develops important social bonds with its mother, littermates and people
  5. Juvenile period
    - 10 weeks to sexual maturity (at around 8 months)
    - adult teeth replace milk teeth at about 5 months (first bottom, then top then molars)
    - removed from moms at the start of this period and continue to develop social relationships with humans and other animals
    - behaviour is similar to the socialization period but more advanced and controlled
    - puberty occurs gradually in males whereas it is more sudden in females at their first heat
