I know GSD are very vocal. My previous ones would talk up a storm. But my current puppy (10 weeks old now) doesn't seem to want to do it. Maybe too young. Maybe she has nothing to say. I am at a loss about her not wanting to sing. She's plenty vocal with barking when she wants something. Playing you tube videos with GSD howling just seems to confuse her. I can't seem to find a trigger to get her to sing.
