All puppies are irresistible.
They retain that charming feature for a very short time before they turn into full-grown dogs. How well you plan for your new dog can make all the difference. Their eyes are sealed closed, and their ears are limited in hearing ability. At 10-14 days, the eyes start to open, and the hearing starts improving rapidly. At 3 weeks, the pups show greatly improved coordination, and they become more aware of and interested in outside stimuli.
