I will tell you about mine, I don't think there your "Typical" GSD's!!
Mine.... are big goof balls!!!

We got both from rescues! So.. they were 5 times the work as a dog that came from a breeder.
Sierra we got when she was 5 months old, (she's 2 now)
and was afraid of men for the first year we had her, and is still head shy of men.
Buddy, we've only had him 9 months, and is still.... we'll lets say he's a Work in Progress!!! We are fighting with the fact that Buddy does not like my hubby!! He's okay with other men, just not Rick. We think Buddy wants to be the man of the house! I think they are FINALLY to the point where we can start doing some general training with Buddy and Rick and try to get those two to make there own bond, and become friends! It's just so hard becaus GSD's want to protect ther owner, and Buddy needs to realize the Rick is his owner too!! Buddy thinks he needs to protect me from my hubby! So..that's a BIG problem right now! It would have been easier maybe had we gotten Buddy earlier in his life! He was already a year old!
But when my hubby is not around, Buddy is an AWSOME dog!! The perfect GSD!! Always protecting me, checking the yard out.
I go for walks with them, and if someone is walking behind us, Buddy will walk sideways so he can keep an eye on them! We have to stop, and let the person pass so we can go on with our walk!! I don't even need to have him on a leash he's such a good boy, and won't leave my side, because then... who would protect me??!!!? Not Sierra!!!!!
Yeah... then there's Sierra.... she'd not so much protective of me, but she's VERY protective of our yard!! She nipps people on the butt on our yard for no good reason!! People will walk through the gate (of our fanced in yard) and she'll follow them for a few steps, then slip behind a tree and watch them, then sneak up behind them and nipp them on the butt and start barking!! Meanwhle, Buddy is barking at them the entire time!!!!!
We had to do something about this, so now we have a huge pen in our yard that they go into when we have people over.

As far as kids.... neither of mine have been around kids. They both have snapped at kids. A group of 7 or 8 year olds were running around screaming playing tag, so I started to walk away from them, and then all at once the gather in a circle around us yelling "CAN I PET YOUR DOGS???" Both got freaked out and snapped at different kids at the same time. I told all the kids to back up, and sat both dogs, and one at a time, had the kids come up and pet them. So they were just spooked, but I didn't like it!!
Now, I have a 2 year old niece that come to visit, and they both seem fine with her, but my sister won't let her get too close to them. But just earlier this am they stopped over, and I gated the pups in my bed room, and Julia (my niece) stuck her arms over the gate and was petting them both, and both had tails wagging and wanted to com out!! Even after a few of her screaches.. (little kids when there SUPER happy) they didn't seem to mind!
I do know that Sierra does NOT like to be chases by little kids! A friend had her 7 year old over and they have a dog that LOVES kids, and I told him that Sierra does not like to be chases, well, he did anyway, and she finally turned and snapped at him. (after I told him to stop 4 times) So...... as for GSD being good with kids, as with any dog, start them early!!!!!!
My two chase eachother around for hours and hours on end!! That's why I have a problem with them keeping weight on!! There both on the skinny side, healthy.... but just skinny the vets say!!! Neither fetch ANYTHING!!! I could throw a raw steak, and they'd both look at me like " What... do you think I'm going to go get that!?!?"
Shedding, LOTS OF HAIR IN THE HOUSE!!!!!!!!!!!! I have to vacuum everyother day!!
So... the one thing I am going to start strong on this winter is training, Buddy is doing pretty good with Rick.
And my brother-in-law just got a new baby girl GSD named Sage, here she is:



and here's my babies!!
