Born after approximately sixty days gestation, a puppy's eyes and ears are sealed shut, and his strongest sense is touch. Warmth is essential, since he can not regulate his body temperature and his nervous system hasn't matured yet.
At about two weeks of age, possibly earlier, his eyes will open, although he still can not see well, and bright light hurts his eyes.
