We have our male GSD from here. He's a Long Coat and just such a great family dog. He's pretty protective though and was the only pup in the litter that actually fetched a ball when she threw it, and retrieved it. It makes it really fun to play with him, but he definitely likes his jobs. I think he knows about 12 different tricks now because I love to challenge him mentally. People joke he's a circus dog, but he LOVES it.
I'd love to hear about more people that got their dogs from this breeder. Ours loved to greet people at the door up until 1yr. old - then instead of thinking they were here for his play time, he started thinking they were coming to kill us all. Nothing really initiated that, but we've definitely had to always put him away when guests come over - especially those that don't like dogs, he's never met before or have kids. He just sees kids as mini strangers even though he was super socialized to them newborn - 16yrs old as a puppy.
Outside of the house and his property, he's a gem (although I still think he gets way too excitable around children) and man after he turned 2yrs. old he's turned into a cuddler. He's 2.5yrs. old now.
