My first GSD Beau (RIP) I got to meet when she was 2-3 days old. We went to the breeders to meet her other pups and got to sneak a peek in on the new litter we were expecting our pup from. My family and I visited every week until 8 weeks when we brought her home. I was about 10-12 then and it was quite the experience.
Stark I met when he was about 4 weeks old, visited a few times per week until he came home at 8 weeks.
Zefra I got to meet extremely early and watch her progress. It was a real treat to see this little sausage grow into a crazy wild puppy.
