  • The puppies can hear better within two weeks
  • As they get stronger, puppies begin to crawl
  • Crawling slowly graduates to walking
  • They start going for potty by themselves

This is the socialization stage where the 3 to 4 week old German Shepherd puppies depend on their mother for socialization.




A 3 to 4 week old German Shepherd puppy still needs the company of its mother even when it reaches weaning age. Interaction with its mother ensures the Shepherd puppy grows into a well-behaved and sociable dog.



The puppy is not ready for adoption yet.

They need to spend more time with the mother to learn how to socialize beyond the litter.


As the puppies learn from their mother, they are also going through notable physiological changes;

  • The puppies can now walk upright
  • Puppies are lively and playful within the litter
  • Most of the teeth have grown at this point
  • Puppy fight or flight responses are checking in
  • The ears are becoming erect and alert

Notable changes in this phase include;

  • All puppy teeth are fully grown
  • Adult teeth are forming
  • Growth continues but slowly

He has an adult body and is beginning to show interest in the opposite sex.

Growth continues even as the German Shepherd dog prepares to have its litter.


If you do not have plans to raise a new litter, this is the best time to spay or neuter your German Shepherd.

This helps in maintaining control of the dog.

Also, spayed or neutered dogs gain and maintain weight faster.


As you interact with your German Shepherd, you will notice these new changes in them;

  • All adult teeth are fully grown
  • The ears are fully erect
  • Puppies start forming strong bonds with each other
  • Females start having their heat cycle while the males become sexually active

Female German Shepherd dogs mature faster and become adults by the 24th month.



💡Fun fact

Even when a German Shepherd reaches sexual maturity, they continue to grow in weight until 36 months.



To guarantee a German Shepherd’s growth within this period, you have to feed them a healthy diet.

Continue feeding them the same brand of high-quality kibble you have been feeding them.

If you want to transition the dog to wet foods, do it gradually and not abruptly to prevent gut issues.


Training should also continue in this period.

This helps the limbs to continue forming and becoming stronger before full adulthood.


Also, teach the dog new and complex commands to keep their minds stimulated.
