Its funny, when we moved here I noticed that while out walking people weren't friendly. I would smile or nod or say hello to people and they would just put their heads down and march past. I figured it was just a German thing and didn't take offense to it. They probably think I'm a little weird or maybe a little special because I'm always smiling at them.
Ever since I started walking with General though I've noticed a complete change. People will smile, nod, or say hello TO ME! Sometimes from all the way on the other side of the street! If they don't do that they at least stare lovingly at General as they pass. This is definitely a dog-friendly country!
