Puppies are functionally blind and deaf at birth. On day one, their eyes are firmly shut and their ear canals closed. Why? In brief, it’s part of an evolutionary trade-off. Since pregnancy can hurt a carnivore's ability to chase down food, dogs evolved to have short gestation periods. Brief pregnancies meant that canine mothers wouldn't need to take prolonged breaks from hunting. However, because dog embryos spend such a short time in the womb (only two months or so), puppies aren't born fully developed—and neither are their eyes or ears.
