I love dogs - German Shepherds are my favorite!  I own 4!  Are you a dog person?
Yes, I also love dogs. The German Shepherd is a new breed of dog, right? I think they have only been around since 1899.
Really?  I didn't know that!  I wonder who discovered them?  They are so affectionate!
I'm not sure who discovered them, but I know they were bred specifically to herd sheep.
Mine love to try to herd the cats and the kids.  They are so gentle with both, it's amazing. 
They also are easily trained, obedient, and intelligent. Because of this, they are often used for disability assistance and for police work.  
I have seen a lot used as police dogs.  I thought because of their sense of smell.
I'd imagine that was helpful too, especially as the other breeds used are Rottweilers and Belgian Malinois 
Rottweilers scare me, though!  I've never heard of Belgian Malinois?
Malinois dog
The Malinois is a medium-to-large breed of dog, sometimes classified as a variety of the Belgian Shepherd dog rather than as a separate breed. The name "Malinois" is derived from Malines, the French name for the breed's Flemish city of origin, Mechelen.
The breed is used as a working dog for tasks including detection of odors such as explosives, accelerants (for arson investigation), and narcotics; tracking humans for suspect apprehension in police work; and search and rescue missions
them that they are not alone. The whole community around the world is standing behind them. They have to trust that if they open their mouth, then we can change something." To a reporter from "The Observer", she commented: "It's funny that these people think I'm so powerful. I've figured out over the years, you can only hurt me if I love you; if I don't know you, I really don't care. There are people who want to kill me
