Stage 1: Neonatal Period (0 – 2 weeks)

Stage 2: Transitional Period (2 – 4 weeks)

Sensory development continues with hearing and sense of smell. Puppy teeth start coming through and their eyes will begin to open. This is also the age where your puppy’s personality begins to develop. Puppies will interact with their litter mates, wag their tails, stand, walk a little and bark.

This is the most important stage of a puppy’s development. It is vital to understand this stage as most puppies go home to their new parents between 7 – 12 weeks. During this period, changes start to occur rapidly.

Between 3- 5 weeks puppies start to become aware of their surroundings and have the ability to develop a relationship with people This is the period where puppies get familiar with the day-to-day noises of a regular household such as TVs, vacuum cleaners, telephones, etc.

Bringing your pup home (usually between 7-12 weeks) is right in the middle of his socialization period. Therefore, it is vital that you introduce your puppy to as many new dogs, people, objects and surroundings as you can. BUT, make sure you do so in a controlled manner and never put your puppy in a dangerous situation where they can be injured, scared or contract disease.

Even though your home is likely puppy proofed, it also saves your possessions.

During this phase of development, puppies are developing their reactions to things much more consistently. They are also likely to focus more on different types of people and should be friendly and approachable to strangers.
