Newborn puppies are completely helpless and yet very adorable. When puppies are born, their eyes are usually closed, and they mostly sleep and crawl around a little.
When they start to become curious, they start to walk. They are more curious about the world once they start to open their eyes and explore it. It usually happens when puppies are around two weeks old. This new ability of sight causes them to become curious about the world, and they soon learn to stand and walk.
