Newborn puppies are tiny, often weighing just a few ounces, and their eyes and ears are sealed shut.
At birth, puppies don't have teeth. Their baby teeth start to emerge at around 3 weeks of age.
Newborns can't regulate their body temperature, relying on their mother's warmth.
Puppies have an incredible sense of smell, even from birth, helping them locate their mother's milk.
During the first few weeks, puppies grow rapidly, and their eyes and ears open, allowing them to explore the world.
Around three weeks old, puppies take their first wobbly steps, an adorable and important milestone.
From a young age, puppies begin to learn and mimic behaviors from their mother and siblings.
