Puppies are born without the sense of sight. At birth, their eyes are closed, and they do not fully develop the ability to see until a few weeks after birth. Their eyes gradually open during the first 1-2 weeks, and their vision continues to develop and improve as they grow. In the early stages of their lives, puppies rely heavily on their sense of smell and touch to navigate and interact with their environment. Over time, as their eyesight matures, they become more visually aware and responsive to their surroundings.
