Which stage corresponds to birth to 2 weeks?

• A. Neonatal Stage
• B. Transitional Stage
• C. Socialization Stage
• D. Ranking Period

Answer: (A)

Birth to two weeks is the neonatal stage. In this period puppies are born blind and deaf and rely entirely on their mother for warmth and nutrition, as well as for stimulating elimination. Movement is minimal and reflexive, and they lack independent control over body temperature. Because the dam provides most of their essential needs, handling and exposure should be very limited to avoid stressing the newborns and disrupting thermoregulation and nursing.

The other stages don’t fit this timeframe. The transitional stage begins as senses start to come online—eyes and ears open and puppies start to move more—usually a little later in the first weeks. The socialization stage happens after that, when puppies become more aware of people and other dogs and begin learning social cues. The ranking period refers to later litter dynamics as puppies establish social order.
