German Shepard Breeders.

Hi op,
It kinda, sorta depends on what you want from your dog? Family pet? Guard dog? (it's almost impossible to get the two reliably in one dog, although even the gentlest of sheps will bark at strangers or unusual goings-on). Show dog? Working dog?
Long coated? Short coated? (huge difference in coat maintenance)
Dog to live in or out? They're a breed that tends to get turfed out to live long hours alone, but I've always found them to really, really crave proximity with their people and they really suffer if left outside.
I have two working sheps. They both live inside the house. They are blissfully happy and content dogs

Just because they're indoor doesn't mean they've to lie on the furniture watching tv! Mine don't get up on the furniture. Neither are they particularly interested in investigating outside unless I'm with them. They just want to be in my vicinity, doing whatever I'm doing, or supervising whatever I'm doing
Do not underestimate the loyalty and devotion of the GSD op... They really do suffer if left alone, and realistically, it's a very rare thing that a pet dog owner who keeps the dog outside, gives it enough attention every day of the year. As choc chip points out, working dogs that are kept outside generally enjoy human company for long hours during the day... They're working together. But pet dogs? Way too easy to let them drop down the list of priorities in the middle of winter, in the peeing rain, and the kids have to get their homework/music lessons/family time done... Inside.
It has also been my overwhelming experience over years of training dogs, that pet dogs who live outside are usually vastly undertrained, and when people do head out to them, or on the odd occasion they're let inside, they get so overawed and excited that they're promptly left alone outside again. Having dog live inside forces you to train it well, and it pays off in huge bucketfuls with such devoted and clever dogs as the GSD.
I've had 3 GSDs from the same lines, and will always have them, because they are utterly bulletproof with everyone and everything. They are laid back, easygoing, gentle to a fault, there quite simply isn't a bad bone in their bodies. They'll still bark at strangers though, but it wouldn't even occur to them to do harm to anyone. I've posted about them before... They're from a line that's really designed to be a PET dog, but can be used for work if need be. They're originally from working lines. They're healthy, straight-backed, great hips, some problems with lower back pain later in life (they're huge dogs, even the females are 40kg+). I've put a fair few people onto this line of GSDs, and I've yet to hear one single complaint... But again, they're all bought with the deal that they're not going to be living outside.
For the record, I wouldn't touch a GSD from show lines. Dodgy both physically and mentally.
