|The apple doesn't fall far from the tree, especially for dogs. The fact is,
well-socialized dogs are more likely to have well-socialized puppies. Pups
often mirror their mothers' calm or fearful attitude toward people; this is a
normal part of their socialization. But you can play a vital role, too, by
petting, talking, and playing with puppy to help him develop good "people
Puppies are usually weaned at six to seven weeks, but are still learning
important skills as their mother gradually leaves them for longer periods of
time. Ideally, puppies should stay with their littermates (or other
"role-model" dogs) for at least 7-8 weeks.
Puppies separated from their littermates too early often fail to develop
appropriate "social skills," such as learning how to send and receive signals,
what an "inhibited bite" (acceptable mouthing pressure) means, how far to
go in play-wrestling, and so forth. Play is important for puppies because it
increases their physical coordination, social skills, and learning limits. By
interacting with their mother and littermates, puppies explore the ranking
process ("who's in charge") and also learn "how to be a dog."
Skills not acquired during the first eight weeks may be lost forever. While
these stages are important and fairly consistent, a dog's mind remains
receptive to new experiences and lessons well beyond puppyhood. Most dogs
are still puppies, in mind and body, through the first two years of life.
Here are general guidelines for puppies' stages of development:
Birth to Two Weeks: Neonatal Period
Puppy is most influenced by his mother.
Senses of touch and taste are present at birth.
Two to Four Weeks: Transitional Period
Puppy is most influenced by his mother and littermates.
Eyes open, teeth begin to come in, and senses of hearing and smell develop.
Puppy begins to stand, walk a little, wag tail, and bark.
By the fourth or fifth week, eyesight is well-developed.
Three to Twelve Weeks: Socialization Period
During this period, puppy needs opportunities to meet other dogs and people.
By 3 to 5 weeks, puppy becomes aware of his surroundings, companions (both
canine and human), and relationships, including play.
By 4 to 6 weeks, puppy is most influenced by littermates and is learning about
being a dog.
From 4 to 12 weeks, puppy remains influenced by littermates and is also influenced
by people. Puppy learns to play, develops social skills, learns the inhibited bite,
explores social structure/ranking, and improves physical coordination.
By 5 to 7 weeks, puppy develops curiosity and explores new experiences. Puppy
needs positive "people" experiences during this time.
By 7 to 9 weeks, puppy is refining his physical skills and coordination, and can begin
to be house trained. Puppy has full use of senses.
By 8 to 10 weeks, puppy experiences real fear involving normal objects and
experiences; puppy needs positive training during this time.
By 9 to 12 weeks, puppy is refining reactions, developing social skills with littermates
(appropriate interactions), and exploring the environment and objects. Puppy begins
to focus on people; this is a good time to begin training.
Three to Six Months: Ranking Period
Puppy is most influenced by "playmates," which may now include those of other
Puppy begins to see and use ranking (dominance and submission) within the
household (the puppy's "pack"), including humans.
Puppy begins teething (and associated chewing).
At 4 months of age, puppy experiences another fear stage.
Six to Eighteen Months: Adolescence
Puppy is most influenced by human and dog "pack" members.
At seven to nine months, puppy goes through a second chewing phase, part of
Puppy increases exploration of dominance, including challenging humans.
If not spayed or neutered, puppy experiences beginnings of sexual behavior.
