I think German Shepards dogs are a wonderful breed. My one is a bitch and is great at guarding the house and garden. She loves to roam around the side drive by the gate and when someone comes to buy eggs, she always lets us know with a bark. Of course our neighbours know her well.
In this YouTube video, a bloke in the USA can walk around with as many as ten German Shepards. Sometimes off the lead, yet they all huddle about him as he walks the streets. How he has managed to train so many is beyond me, but they make for a very fine sight.
