Dog trainers please help! My puppy is too shy!?

[symington]

At 3 months your shepherds drives are already in full force. A DS pup would already be guarding the hell out whatever it perceives as his duty. 100% of shepherds do NOT have the same drives.

You can socialize him to make him less shy and train guard like behaviors, but you can not create drive.

It sounds like a good thing. YOU do not want a high drive dog if you have no idea what you are doing. A dutch shepherd can be very dangerous if it is high drive and not handled properly.
