When Can Newborn Puppies See. Newborn puppies can start hearing around 2 to 3 weeks of age, responding to loud noises. In mild weather, even newborn puppies can be taken out to your own garden or backyard, as long as they're supervised and confined to a small, safe area.

If you are weighing the puppies regularly (once a day), there should be a consistent increase in weight. But going outside is an important part of a puppy's development. Only after 4 weeks, puppies can start to see clearly.
