Newborn puppies are born blind and deaf. Their eyes don't open until they're about 2 weeks old, and their hearing develops around the same time.
Newborn puppies can't regulate their body temperature on their own. They need to stay close to their mother to stay warm.
Newborn puppies can only eat milk. Their mother's milk provides them with the nutrients they need to grow and develop.
Newborn puppies have a soft spot on their head called an "fontanel." This is where the bones of their skull haven't fused together yet.
Newborn puppies need to be fed every 2-3 hours. This is because their stomachs are very small and they can't hold a lot of food at once.
Even though they're still very young, newborn puppies are already very playful. They love to chase each other and play with toys.
Newborn puppies bond quickly with their mother. They rely on her for food, warmth, and protection.
