The Crucial Second Week: Developmental Milestones for Puppies

Updated: Jun 22, 2023

The 2nd week is a crucial week as puppies reach several developmental milestones. During this time, they undergo significant physical, mental, and social changes that set the foundation for their future well-being. In this blog, we will take a closer look at what happens during the second week of a puppy's life.

Physical Changes

During the second week, puppies start to open their eyes. The eyes are still closed at the beginning of the week, but they begin to peek out by the end of it. The puppies' ears also start to open, allowing them to hear sounds for the first time. This is an exciting time for the puppies as they begin to explore their surroundings using their newly discovered senses. Puppies also gain weight rapidly during this week. They should double their birth weight by the end of the second week. It is essential to ensure that the mother is providing enough milk for the puppies to grow and thrive. If not, supplemental feeding may be necessary.

Mental Changes

Puppies' brains continue to develop rapidly during the second week. They become more aware of their surroundings and are more responsive to stimuli. They start to learn basic skills such as walking, standing, and even a little bit of play. The puppies' brains are like sponges, soaking up information and learning new things every day.

Social Changes

During the second week, puppies begin to interact more with their littermates and mother. They start to play with each other, exploring their environment and learning social skills. They also learn bite inhibition, which is essential for proper socialization and

to prevent aggressive behavior later in life. It is crucial to expose the puppies to different people and environments during this time to help them develop good social skills. This exposure will help them become more adaptable and better able to handle new situations.


The second week of a puppy's life is a critical period of growth and development.

Puppies undergo significant physical, mental, and social changes that set the foundation for their future well-being. As a puppy owner, it is essential to provide a safe and nurturing environment for the puppies during this time. By doing so, you can help them develop into happy, healthy adult dogs.
