Puppies lack two senses at birth: sight and
hearing For their development requires at least 10 days, and sometimes
few weeks. Although the lack of vision and hearing may seem
strange for you and me, puppies develop in a way that
formed as a result of evolution and beneficial to their species. But why so
is going on? And when the eyes of puppies open?

Why puppies рождаются слепыми и глухими?
When you look at newborn puppies, they seem so
helpless and small. The idea that they are born deaf (with
closed ear canals) and blind (with closed eyelids), it seems
makes no sense. Why does evolution allow an animal
born in a state where his two main feelings are not
functioning and can not give important information about the world?
The gestation period in dogs is short, only about two months from
58 to 63 days on average. Many of the puppy’s critical organs,
including his brain, are not fully formed, and they will
catch up, developing rapidly over the course of
a few weeks after birth. The same goes for the eyes.
Therefore, the reason why puppies are born blind is as follows: an eye
still developing, and at the time of birth it is extremely fragile.
To protect an immature optical system from potential
damage by external stimuli such as dirt, sand
or microorganisms, eyes require protection. Its just
provide closed eyelids. Exposure to too bright light too
can damage the delicate photoreceptors of the eyeball.
Puppies are born not only blind, but also deaf, because
their ear canals are closed. Relative silence is important to
developing ears since sounds are associated with pressure changes.

so sometimes puppies can open their eyes a day or two earlier or
later. It depends on the individual pet. Sometimes in the same litter
one puppy can open his eyes after 9 days, another after 14 days,
third after 18 days. Also, the baby can open one eye earlier,
than the other. However, the opening of the eyes does not mean that they are completely
developed and ready to function. Eyes will first
