Hi
I had GSD'S for many years and will always have a love of the breed, I have BMD's now due to a change in circumstances, but will always love the GSD.
They are not "One man dogs" but are a truly committed family dog, enveloping the whole family into their "Pack". Like any breed care needs to be taken when finding one and obviously good health and excellent character are to be looked for in Mum and Dad. Make sure all the relevant health tests are up to date and in accordance with the breed requirements.
Brought up with respect and gentle training with plenty of socialisation as pups,and you will reap the reward of having a dog who is loyal sociable and quick to learn. I found they were quite high energy dogs who thrived on lots of exercise, they learn fast and need to have something to occupy their minds as well as their bodies. A life of two 20 min walks a day and nothing else to use their brains on will produce a dog capable of immense unruliness. They thrive on obedience, agility, working trials, or even just lots of active play-times. They never take their eyes off you when out walking, and all though can range far away will know exactly where you are at all times.
They will give their all to their family and will protect by nature (Not a thing anyone needs to train them to do...it comes natural! you look after them properly and they will look after you ,God forbid...if it ever became necessary ) They can be the most wonderful easy going well trained softies or a bundle of insecurity, and fear, they can become aggressive and unmanageable if not treated fairly in all ways. They are pretty tolerant of other dogs of either sex if socialized as pups, I have only one male who was a holy terror due to his being on Very very restricted exercise as a pup , with HD (Throw back, not the breeders fault but unfortunately very bad) he suffered pain and lack of any viable socialization apart from my other dogs. However he lived to 14 ish and never hurt anyone though he needed careful handling and lots of training. After the first year he led a pain-free life with his hips, but the advice from the vet at the time to restrict him so much did him no favours with his social skills!
At their best they are "All things to all men" at their worst they can be very difficult to live with and being a big breed are capable of a lot of damage.
If you are prepared to give them your all, then you will not be disappointed, but if you just want a couch potato....well try another breed!
Hope this helps, it is just my opinion based on the GSD's I have known and loved.
