Mother Dog Saves Puppies From Fire, Santa Rosa De Temuco, Chile

Puppies develop very quickly during their first three months, particularly after their eyes and ears open and they are no longer completely dependent on their mother. Their coordination and strength improve, they spar with their litter-mates, and begin to explore the world outside the nest. They play wrestling, chase, dominance, and tug-of-war games. Puppies are highly social animals and spend most of their waking hours interacting with either their mother or littermates.
It is important that puppies are socialized with humans, particularly between the ages of eight and twelve weeks, so as to encourage healthy interaction and develop the puppy's social skills around people. Puppies ideally should be exposed to as wide a variety of friendly people as possible during this period. Dogs that do not receive adequate socialization during this sensitive period may display fearful behavior around humans or other dogs as adults.
