German Shepherd Females that are used for breeding should be trained. This is a true test of the temperament and workability!
Here is the reason why:
Genetics between two parents are biologically 50/50, the great mothers come more into play than the father as they raise the puppies!
Most puppies never see their father!
Once their eyes and ears open in small increments, they only see their mother.
Imagine that a mother is not of stable temperament. A stranger aproaches, and she hides behind the dog house.
What are the puppies going to do?
They will do what they see-not what they are told Just like little kids!
The mother’s behavior inprints the puppies’ temperament.
