The German pups are known to have different standards in comparison to the American ones. The German ones tend to be a little larger and have long tails. In the U.S, breeders still favor the docked tail.
Thanks to its history as a herder, the dog has a habit of bumping into people, animals, and things when it wants them to fall in line.
Being highly trainable and capable of performing a variety of tasks, they often work as tracking, rescue, therapy, and service dogs for police, military, and hospitals.
