Can puppies hear or see first? How Your Puppy’s Eyes Develop. When puppy eyes first open they start out with a milky, grayish-blue appearance but that clears with time. A puppy’s eyes don’t truly mature until the animal is 4–5 weeks old. In fact, puppies can see before they can hear (their ears open at around 18–20 days), Todd says.
What senses are puppies born with? Olfaction is a puppy’s only major sense for the first few weeks of life. Puppies must find their siblings, mom and milk by using smell, not with vision or hearing. A large part of the puppy brain called the olfactory bulb is much larger and more developed than that of people.
Can you touch puppies when they are born? Once the puppies are about three weeks old, they will begin to move around on their own. This is when you can begin to pet them and interact with them more. You should only touch or pick up a newborn puppy if you observe that it is sick, if the mother abandons it, or in the case of orphaned puppies.
Why can’t puppies hear when they’re born? In the same way that the puppies are born with their eyes closed, they are born effectively deaf because their ear canals are closed. The relative silence is important for developing ears because sounds involve changes in pressure that mechanically move structures in the mature ear.
