They Can’t See or Hear, but They Can Make Noise
Puppies can’t see or hear for the first two weeks of their lives, but they can make puppy noises. “They’ll vocalize right from the beginning,” Wheeler says. “When they are born, the mom will lick the placenta off to stimulate them.”
At around 10 days, they’ll start to open their eyes, even though they aren’t fully formed yet. “The rudimentary eyeball hasn’t formed completely until up to 10 weeks,” Wheeler describes. All puppies are born with a blue-gray color to their eyes, Casal adds. Their “true” eye color will be evident at around 10 weeks.
As for hearing, Casal says, “Most newborn puppies can hear a little bit when they are born. However, their ears are still closed until about 14 days of age.”
